SYNOPSIS

#include <libexplain/truncate.h>
void explain_truncate_or_die(const char *pathname, long long length);

DESCRIPTION

The explain_truncate_or_die function is used to call the truncate (2) system call. On failure an explanation will be printed to stderr , obtained from explain_truncate (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_truncate_or_die(pathname, length);

pathname

The pathname, exactly as to be passed to the truncate (2) system call.

length

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

Returns:

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