NAME
pfm_get_version - get performance monitoring library version
SYNOPSIS
#include <perfmon/pfmlib.h>
int pfm_get_version(unsigned int *version);
DESCRIPTION
This function can be called at any time to get the revision level of
the library. The version is encoded into an unsigned integer and
returned in the version argument. A revision number is composed of two
fields: a major number and a minor number. Both can be extracted from
the returned argument 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 returns whether or not it was successful. A return value
of PFMLIB_SUCCESS indicates success, otherwise the value is the error
code.
ERRORS
PFMLIB_ERR_INVAL
the argument is invalid, most likely a NULL pointer.
