Troubleshooting Your Application Using A/P API Tracing environment variables on the first valid APRI call (always ap_open) and then set the global API trace variables according to the value of the environment variables. If no environment variables are present, then no API tracing takes place. Environment Variable Names The names of the ACSE/Presentation (AP) environment variables available are as follows: AP_TRACE AP_TRACE_FILE AP_TRACE_MAX_UDATA See "Trace Output" for the effects of these environment variables. AP_TRACE:. The value defined for this variable indicates the trace level to be used for each API call. It is actually a set of flags, defined in the file /usr/ include/api_trace.h. Default = 0 (trace_off). You may set this value in one of two ways: 1. It may be treated as an integer value and may be set using either decimal or hexadecimal notation, for example: AP_TRACE=0xff 2. It may be treated as a set of ASCII flags. The following standard flags are defined. i = input parameters o = output parameters x = external procedure entry exit e = error tracing n = internal tracing AP_TRACE_FILE:. The name of the file that is to receive tracing results. Default = stderr. Chapter 5 69
