VCSAgCloseFile

voidout VCSAgCloseFile(void *vp);

Use this API to push a thread cancellation cleanup handler for an open file descriptor. The API accepts a FILED file descriptor as parameter. The API closes the file descriptor passed as argument. It does not check if the fd is valid (>= 0).

FILED fd = open("<filename>", ...);
if (fd >= 0) {
    pthread_cleanup_push(VCSAgCloseFile, (void *) fd);
    // Use fd
    pthread_cleanup_pop(1); // Run VCSAgCloseFile to close the file
descriptor
}
else {
    // error, could not successfully open file
}
