VCSAgCloseFp

void VCSAgCloseFp(void *vp);

Use this API to push a thread cancellation cleanup handler for an open FILE*, usually returned by library calls like fopen() on UNIX. The API accepts a FILE * file pointer as parameter. The API closes the FILE *. It does not check if the FILE * is valid (non-NULL).

FILE * fp = fopen("<filename>", ...);
if (fp != NULL) {
    pthread_cleanup_push(VCSAgCloseFp, (void *) fp);
    // Use fp
    pthread_cleanup_pop(1); // Run VCSAgCloseFp to close the FILE *
}
else {
    // error, could not successfully open file
}
