-
[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;
{
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)
{
exit(1);
}
// Start counting
ret = PAPI_start(EventSet);
if (ret != PAPI_OK) handle_error(ret);
add PAPI preset or native hardware event to an event set
Create a new empty PAPI EventSet.
