Synopsis

#include <libexplain/ftruncate.h>

void explain_ftruncate_or_die(int fildes, long long length);

Description

The explain_ftruncate_or_die function is used to call the ftruncate(2) system call.  On failure an explanation will be printed to stderr, obtained from explain_ftruncate(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_ftruncate_or_die(fildes, length);
fildes

The fildes, exactly as to be passed to the ftruncate(2) system call.

length

The length, exactly as to be passed to the ftruncate(2) system call.

Returns:

This function only returns on success. On failure, prints an explanation and exits.
