       pfm_get_version - get library version

SYNOPSIS         top

       #include <perfmon/pfmlib.h>

       int pfm_get_version(void);

DESCRIPTION         top

       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:

              returns the major number encoded in v.

              returns the minor number encoded in v.

RETURN         top

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