NAME¶
explain_gettimeofday_or_die - get time and report errors
SYNOPSIS¶
#include <libexplain/gettimeofday.h>
void explain_gettimeofday_or_die(struct timeval *tv, struct timezone *tz);
DESCRIPTION¶
The
explain_gettimeofday_or_die function is used to call the
gettimeofday(2) system call. On failure an explanation will be printed
to
stderr, obtained from
explain_gettimeofday(3), and then the
process terminates by calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion similar to the following
example:
explain_gettimeofday_or_die(tv, tz);
- tv
- The tv, exactly as to be passed to the
gettimeofday(2) system call.
- tz
- The tz, exactly as to be passed to the
gettimeofday(2) system call.
- Returns:
- This function only returns on success. On failure, prints
an explanation and exits.
