i meant the following code.
struct timespec mono will be used after the end of the block.
is it safe?

                if (pthread_cond_getclock(cond) == CLOCK_MONOTONIC) {
                        struct timespec mono, real;
                        if (clock_gettime(CLOCK_REALTIME, &real) == -1 ||
                            clock_gettime(CLOCK_MONOTONIC, &mono) == -1)
                                return errno;
                        timespecsub(abstime, &mono, &mono);
                        timespecadd(&mono, &real, &mono);
                        abstime = &mono;
                }
