       PAPI_perror -

       Produces a string on standard error, describing the last library error.

SYNOPSIS

Detailed Description

       C Interface:
           #include <papi.h>
            void PAPI_perror( const char *s );

       Parameters:
           s -- Optional message to print before the string describing the last error message.

       The routine PAPI_perror() produces a message on the standard error output, describing the
       last error encountered during a call to PAPI. If s is not NULL, s is printed, followed by
       a colon and a space. Then the error message and a new-line are printed.

       Example:

           *  int ret;
           *  int EventSet = PAPI_NULL;
           *  int native = 0x0;
           *
           *  ret = PAPI_create_eventset(&EventSet);
           *  if (ret != PAPI_OK)
           *  {
           *     fprintf(stderr,
           *     exit(1);
           *  }
           *  // Add Total Instructions Executed to our EventSet
           *  ret = PAPI_add_event(EventSet, PAPI_TOT_INS);
           *  if (ret != PAPI_OK)
           *  {
           *     PAPI_perror( "PAPI_add_event" );
           *     exit(1);
           *  }
           *  // Start counting
           *  ret = PAPI_start(EventSet);
           *  if (ret != PAPI_OK) handle_error(ret);
           *
