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.
