PAPI_perror(3)

okay so welcome to PAPI_perror(3) from the PAPI manual — the page that's literally here to help you print a cute little error string on standard error 💖✨

🌸 NAME 🌸

PAPI_perror — produces a string on standard error, describing the last library error. It's giving "tell me what went wrong but make it readable," no cap 💅

✨ SYNOPSIS ✨

The actual C interface is chillin' under Detailed Description below, bestie — keep scrolling 👇🫶

💫 Detailed Description 💫

💻 C Interface: 💻

#include <papi.h>
void PAPI_perror( const char *s );

🎀 Parameters 🎀

• s — an optional message to print before the string describing the last error message. It's your little pre-error hype text, y'know? 💬

So 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, then s is printed, followed by a colon and a space. Then the error message and a new-line are printed. Literally the whole routine is "error? but make it a vibe check" 😭💅

🌈 Example: 🌈

ok so here's the example, verbatim bestie — no cap:

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);
