NAME¶
PAPI_library_init -
initialize the PAPI library.
SYNOPSIS¶
Detailed Description¶
@param 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. @retval PAPI_EINVAL
papi.h is different from the version used to compile the PAPI library. @retval PAPI_ENOMEM
Insufficient memory to complete the operation. @retval PAPI_ECMP
This component does not support the underlying hardware. @retval 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() . @par 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) *
