Enable ROSE API Tracing

To enable ROSE tracing in your program, add the following statements
to your program:
1. Include the appropriate definitions by adding these lines:
Chapter 5
#include <stdio.h>
#include <api_trace.h>
extern int rose_trace;
extern int rose_trace_max_udata;
extern FILE *rose_trace_fp;
Troubleshooting Your Application
Traces procedure entry and exit. No
parameter information is displayed. This is
useful if you are only interested in seeing
what ROSE calls your program is making.
Note that this trace is automatically
generated if you use API_TR_INPUT,
API_TR_OUTPUT, or
API_TR_INT_ENTRY_EXIT.
Provides traces of ROSE function call input
parameters. This is useful if you want to
verify that ROSE is actually receiving the
values you expect.
Provides traces of ROSE function call
output parameters. This is useful if you
want to verify what values ROSE is passing
back to your program.

do so by your HP support representative.
