initialize the PAPI library. More...
|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.|
|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() .
