PAPI_perror(3)

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, 'PAPI error %d: %s\n', ret, PAPI_strerror(retval));
         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);
