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
       operate.  This function probes the underlying hardware looking for valid PMU event  tables
       to activate.  Multiple distinct PMU tables may be activated at the same time.

       The  function  must be called only once. If the function is called more than once, it does
       not execute the initialization multiple times, it simply returns the same value as for the
       first call.

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.
