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)    
*
