NAME¶
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.
