pfm_get_version — get library version

Synopsis

#include <perfmon/pfmlib.h>

int pfm_get_version(void);

Description

This function can be called at any time to get the revision level of the library. It is not necessary to have invoked pfm_initialize() prior to calling this function.

The revision number is composed of two fields: a major number and a minor number. Both can be extracted using macros provided in the header file:

PFMLIB_MAJ_VERSION(v)
returns the major number encoded in v.
PFMLIB_MIN_VERSION(v)
returns the minor number encoded in v.

Return

The function is always successful, i.e., it always returns the 32-bit version number.
