Detailed Description

C Interface:
#include <papi.h>
void PAPI_perror( char *s );
Parameters
[in]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);
