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.
