RPC Sample Code

Sample code for interfacing with the CMM through RPC is available in the file cli_client.c. The
sample code compiles into a command-line executable for use with Linux or a .o file for use with
VxWorks. To select the appropriate target, remove the comment from the appropriate #define in the
source code.
The sample code first authenticates to the CMM through GetAuthCapability(). When the
authentication is successful, the user's command-line arguments (for Linux) or calling parameters
(for VxWorks) are passed to the CMM through ChassisManagementApi(). The return code is then
checked and the result is printed to the console.

RPC Usage Examples

Table 85 presents examples of using RPC calls to get and set fields on the CMM. Data returned by
RPC calls are returned in the ppvbuffer and uReturnType parameters to ChassisManagementApi().
Table 85. RPC Usage Examples (Sheet 1 of 3)
Example
Get the
chassis
temperature.
Get the fan
tray presence.
Get the CPU
temperature
of blade 5.
Determine if a
certain blade
is present.
Get all
thresholds for
the +3.3 V
sensor on
blade 2.

Remote Procedure Calls (RPC)
ChassisManagementApi() [out] Parameters
uReturnType: DATA_TYPE_STRING
ppvbuffer: A null-terminated string of the format:
Value [Units]
uReturnType: DATA_TYPE_INT
ppvbuffer: Integer value indicating presence
1 = Present
0 = Not Present
uReturnType: DATA_TYPE_STRING
ppvbuffer: A null-terminated string of the format:
Value [Units]
