PAPI_library_init(3) PAPI PAPI_library_init(3)NAMEPAPI_library_init-
initialize the PAPI library.
SYNOPSISDetailed Description
Parameters:
version upon initialization, PAPI checks the argument against the
internal value of PAPI_VER_CURRENT when the library was compiled.
This guards against portability problems when updating the PAPI
shared libraries on your system.
Return values:
PAPI_EINVAL papi.h is different from the version used to compile
the PAPI library.
PAPI_ENOMEM Insufficient memory to complete the operation.
PAPI_ECMP This component does not support the underlying hardware.
PAPI_ESYS A system or C library call failed inside PAPI, see the
errno variable.
PAPI_library_init() initializes the PAPI library. PAPI_is_initialized()
check for initialization. It must be called before any low level PAPI
functions can be used. If your application is making use of threads
PAPI_thread_init must also be called prior to making any calls to the
library other than PAPI_library_init() .
Examples:
int retval;
retval = PAPI_library_init(PAPI_VER_CURRENT);
if (retval != PAPI_VER_CURRENT && retval > 0) {
fprintf(stderr,'PAPI library version mismatch!\n');
exit(1); }
if (retval < 0)
handle_error(retval);
retval = PAPI_is_initialized();
if (retval != PAPI_LOW_LEVEL_INITED)
handle_error(retval)
