\fBParameters\fP
.RS 4
\fIversion\fP 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\&.

int retval;
retval = PAPI_library_init(PAPI_VER_CURRENT);
if (retval != PAPI_VER_CURRENT && retval > 0) {
fprintf(stderr,"PAPI library version mismatch!\\en");
exit(1); }
if (retval < 0)
handle_error(retval);
