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.
XTI_TRACE=0xff or XTI_TRACE=255
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 **
* not supported by XTI
** minimal support by XTI
