According to the SunOS 5.5 man page:
NAME
gettimeofday, settimeofday - get or set the date and time
...
RETURN VALUES
A -1 return value indicates that an error occurred and errno
has been set.
Ultrix (4.3) and IRIX (5.3) man pages state that -1 indicates error and 0
indicates success.
The portable thing to do seems to be checking the return value against -1.
This will work with the cygnus implementation.
if (gettimeofday(tvp, NULL) == -1) {
printf("failed\n error was : %s\n", strerror(errno));
} ...
