Using ACSE/Presentation This chapter provides a sample session using ACSE/Presentation between two processes in synchronous mode.
Page 30: Synchronous Acse/Presentation
Using ACSE/Presentation Synchronous ACSE/Presentation Synchronous ACSE/Presentation ACSE/Presentation calls block until the call is complete in synchronous mode. See the section, “Using Synchronous vs. Asynchronous Mode” in chapter 4 for more information. In order to use the ACSE/Presentation service, the processes do the following: 1.

Page 33: Step 1: Create A Communication Endpoint
Using ACSE/Presentation Step 1: Create a Communication Endpoint Step 1: Create a Communication Endpoint Process A and Process B must both create communication endpoints as shown in Figure 3-1, using the call ap_open(). A communication endpoint is a ﬁle descriptor (fd) which is returned on successful completion of the ap_open() call.
Page 34: Step 2: Establish An Association
Using ACSE/Presentation Step 2: Establish an Association Step 2: Establish an Association The steps to establish an association are described below. Initialize the A/P Environment To use the A/P services, each process must initialize the ACSE/Presentation environment by calling ap_init_env(). (See Figure 3-2.) The ap_init_env() call allocates memory for the environment attributes, and sets the attributes to default values.
Page 35: Establish Initiator And Responder Roles
Using ACSE/Presentation Step 2: Establish an Association Establish Initiator and Responder Roles Process A and Process B establish initiator and responder roles using the attribute, AP_ROLE_ALLOWED in a call to ap_set_env(). In this example, Process A is the initiator, and Process B is the responder. (See Figure 3-3.) Figure 3-3 Establish Roles...
Page 36: Set Up The Data Transfer Environment
Using ACSE/Presentation Step 2: Establish an Association APRI also supports the binding of the local presentation address without specifying a network address. This allows a single responder to receive association indications for any of the subnetworks conﬁgured on an OTS/ 9000 system.
Page 37: Request The Association
Using ACSE/Presentation Step 2: Establish an Association Process A calls ap_set_env() using the AP_CNTX_NAME attribute to identify the application context name. Process A then calls ap_set_env() using the AP_PCDL attribute to propose transfer syntaxes for each proposed abstract syntax that will be used for data transfer between Process A and B.

Page 39 Using ACSE/Presentation Step 2: Establish an Association Process B can reject the connection if the proposed transfer syntax is not supported by setting the res ﬁeld in structure ap_cdrl_t to USER_REJ or PROV_REJ and prov_rsn is the reason for the reject. If the process cannot accept the association request for other reasons, the process sets the reason using the A_ASSOC_RSP primitive.
Page 40: Step 3. Exchanging Data
Using ACSE/Presentation Step 3. Exchanging Data Step 3. Exchanging Data Once an association is established, processes can send and receive control data (primitives) and user data. It is the responsibility of the process to encode and decode data with the selected transfer syntax.

Page 42: Step 4: Release The Association
Using ACSE/Presentation Step 4: Release the Association Step 4: Release the Association Processes must cooperate to ensure that no data is lost when the association is released. This can be accomplished by requesting a release, accepting the release, then terminating the association. Requesting the Release After Process A has completed sending user data, it sends a release request to Process B using ap_snd() with the A_RELEASE_REQ...
Page 43 Using ACSE/Presentation Step 4: Release the Association The process closes the association until it receives the positive release response from Process B. Process A monitors events with ap_poll() and receives the response by calling ap_rcv(). If an association is released abnormally, for example, if a lower layer problem occurs, a provider abort (A_PABORT_IND primitive) may be received.
Page 44: Step 5: Closing The Communication Endpoint
Using ACSE/Presentation Step 5: Closing the Communication Endpoint Step 5: Closing the Communication Endpoint Finally, both processes use ap_close() to close down the communication endpoint (ﬁle descriptor) and A/P environment resources (see Figure 3-11). If the association is still alive when ap_close() is invoked, the association will be aborted by the provider before the communication endpoint is released.

Page 47 Programming Guide Summary of Programming Tasks 5. Decide if multiple associations need to be supported. The process accepting multiple connections needs to create additional communication endpoints and instances of the A/P environment. Review the paragraphs describing: execution mode, connection retry, and maximum number of connections supported (system, processes, and other applications).
Page 48: Prepare The System
Programming Guide 1. Prepare the System 1. Prepare the System Before you use the ACSE/Presentation interfaces, make sure that the following has been done: • Verify HP OTS/9000 h as been installed correctly. • Check that the presentation addresses, in particular, the local NSAP(s) used by the ACSE/Presentation applications that have been conﬁgured in the OTS conﬁguration ﬁle.
Page 49: Manage The A/P Environment
Programming Guide 2. Manage the A/P Environment 2. Manage the A/P Environment The ACSE/Presentation environment contains the necessary information to establish and maintain an association. The primitives used to identify this information are called attributes. See Appendix A, “AP_ENV Table of Attributes”...
Page 50: Determine Address Handling
Programming Guide 2. Manage the A/P Environment On the other hand, when the connection indication is received by the other process, it is established as the responder, and can no longer issue a connection request. The AP_ROLE_CURRENT is automatically set to AP_RESPONDER.

Binding can only be done in the AP_UNBOUND state. A/P supports extended addressing which provides for the maximum address lengths for each selector in the presentation address as shown in the following table: Table 4-1 Selector Maximum Lengths...
Page 52: Portability, Migration Considerations
Programming Guide 2. Manage the A/P Environment Application Contexts (AP_CNTX_NAME) Associations must negotiate the application contexts used. The initiator proposes a service or services to run, and the responder must reply to accept or reject the context. This is a mandatory parameter in the OSI ACSE layer.
Page 53 Programming Guide 2. Manage the A/P Environment • Isolate the allocations and freeing of memory passed to the A/P library to a single function. For example: void *ubuf_ptr; user_get_osi_buf (&ubuf_ptr, len,”data to put in ubuf”); ap_snd (.., ubuf_ptr); • Do not statically initialize a cdata structure. For example, do not use the statement: a_assoc_req_env_t peer_application = {...};...
Page 54: Managing Data
Programming Guide 3. Managing Data 3. Managing Data ACSE/Presentation (A/P) deﬁnes two types of data: control data and user data. Control data (cdata) is associated with the primitives and its content is speciﬁc to each primitive. User data (ubuf) is managed by the application and is deﬁned by the context and transfer syntax selected.
Page 55: User Data Encoding/Decoding
Programming Guide 3. Managing Data 1) First ap_snd() set AP_MORE, and send data 2) Additional ap_snd()'s set AP_MORE, and send data 3) Last ap_snd() re-set AP_MORE, and send last data When receiving data, the AP_MORE bit is set by the A/P library if the receiving ubuf is not large enough, or if a partial primitive was received.
Page 56: Using Synchronous Vs. Asynchronous Mode
Programming Guide 4. Using Synchronous vs. Asynchronous Mode 4. Using Synchronous vs. Asynchronous Mode ACSE/Presentation supports both synchronous and asynchronous mode execution of calls. In synchronous mode, an ACSE/Presentation call blocks until the call can be completed. While blocked, no other tasks can be performed.
Page 57: Changing Modes
Programming Guide 4. Using Synchronous vs. Asynchronous Mode If ap_rcv() is called in asynchronous mode, data is read from the communication endpoint until either: • the entire primitive is received • the ubuf argument buffer is full • no more user data is available. In the second case, the AP_MORE bit is set in the ﬂags parameter of ap_rcv().
Page 58: Managing Multiple Connections
Programming Guide 5. Managing Multiple Connections 5. Managing Multiple Connections Before writing an application with multiple connections, you may need to consider the following items: • Execution mode • Connection retry • Resource constraints Execution Mode For using multiple connections, asynchronous mode is recommended. Using multiple connections introduces factors that cannot be controlled such as: when a task will complete, how long a task will take, or whether or not tasks will complete sequentially.

Page 60: Connection Retry
Programming Guide 5. Managing Multiple Connections Connection Retry When there is a resource shortage, ap_snd() may return AP_AGAIN. The application should re-send the same primitive as outlined in the ap_snd() manpage. NOTE In the case of a connection request (A_ASSOC_REQ), if a resource shortage occurs in the OTS stack, a reject may be received as a A_PABORT_IND or A_ABORT_IND.
Page 61: System Maximums
Programming Guide 5. Managing Multiple Connections Note that if an ACSE/Presentation call (such as ap_open()) fails because of temporary memory shortage, the application may want to retry the same call later. System Maximums OTS supports up to 4096 virtual circuit (VC) connections at the transport and network layer (X.25 CONS).
Page 62: Other Tasks
Programming Guide 6. Other Tasks 6. Other Tasks Other items to consider in developing A/P applications include: • File descriptors • Signal handling • Error checking File Descriptors Communication endpoints for ACSE/Presentation applications are HP-UX ﬁle descriptors. Because of unpredictable results, HP recommends you do not use HP-UX ﬁle system calls such as exec(2), dup(2), read(2), write(2), ioctl(2), or select(2) with HP OTS/9000 A CSE/Presentation ﬁle descriptors.
Page 63: Error Checking Routines
Programming Guide 6. Other Tasks Signal handlers can be written to capture signals and exit, or to prevent signals from interrupting critical call sequences. Error Checking Routines Along with processing signals, ACSE/Presentation applications need to check for return codes from calls and particular error conditions that are returned.
