NAME         top

       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.
