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( 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, \"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);
