NAME explain_truncate_or_die - truncate a file and report errors
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.
