it opens and writes to /dev/tty...
so what does this mean?
does it mean that (STDIN_FILENO) points to /dev/tty under normal conditions, but stdin does not? then where does it point to?
why did i have to open "stdin"'s fd to write to it? because i never have to open "stdout"'s fd to write to it...

papi_strerror
PAPI_strerror(3) PAPI PAPI_strerror(3)NAME
PAPI_strerror -
Returns a string describing the PAPI error code.
SYNOPSIS Detailed Description
C Interface:
#include <papi.h>
char * PAPI_strerror( int errorCode );
Parameters:
code -- the error code to interpret
Return values:
*error -- a pointer to the error string.
NULL -- the input error code to PAPI_strerror() is invalid.
PAPI_strerror() returns a pointer to the error message corresponding to the error code code. If the call fails the function returns the
NULL pointer. This function is not implemented in Fortran.
Example:
* int ret;
* int EventSet = PAPI_NULL;
* int native = 0x0;
* char error_str[PAPI_MAX_STR_LEN];
*
* ret = PAPI_create_eventset(&EventSet);
* if (ret != PAPI_OK)
* {
* fprintf(stderr, "PAPI error %d: %s0, 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");
* fprintf(stderr,"PAPI_error %d: %s0, ret, error_str);
* exit(1);
* }
* // Start counting
* ret = PAPI_start(EventSet);
* if (ret != PAPI_OK) handle_error(ret);
*
