NAME
       pfm_initialize - initialize library

SYNOPSIS
       #include <perfmon/pfmlib.h>

       int pfm_initialize(void);

DESCRIPTION
       This  is  the  first function that a program must call otherwise the library will not function at all.  This function probes the underlying
       hardware looking for valid PMUs event tables to activate.  Multiple distinct PMU tables may be activated at the same time.

       The function must be called only once.

RETURN
       The function returns whether or not it was successful, i.e., at least one PMU was activated. A return  value  of  PFMLIB_SUCCESS  indicates
       success, otherwise the value is an error code.

ERRORS
       PFMLIB_ERR_NOTSUPP
	      No PMU was activated.
