PROLOG
       This manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may dif-

       #include <sys/time.h>

       fied.

       If tzp is not a null pointer, the behavior is unspecified.

RETURN VALUE
       The gettimeofday() function shall return 0 and no value shall be reserved to indicate an error.
