NAME
explain_ftruncate_or_die - truncate a file and report errors
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.
