explain_usleep_or_die

NAME

explain_usleep_or_die − suspend execution for ms intervals and report errors

SYNOPSIS

#include <libexplain/usleep.h>
void explain_usleep_or_die(long long usec);
int explain_usleep_on_error(long long usec);

DESCRIPTION

The explain_usleep_or_die function is used to call the usleep(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_usleep(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

The explain_usleep_on_error function is used to call the usleep(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_usleep(3) function, but still returns to the caller.

RETURN VALUE

The explain_usleep_or_die function only returns on success, see usleep(3) for more information. On failure, prints an explanation and exits, it does not return.

The explain_usleep_on_error function always returns the value return by the wrapped usleep(3) system call.

EXAMPLE

The explain_usleep_or_die function is intended to be used in a fashion similar to the following example:

explain_usleep_or_die(usec);
