NAME
       PAPI_perror -

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

SYNOPSIS
Detailed Description
       C Interface:
	   #include <papi.h>
	    void PAPI_perror( 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);
	   *
