NAME

explain_lchmod_or_die - change permissions of a file and report errors

SYNOPSIS

#include <libexplain/lchmod.h> void explain_lchmod_or_die(const char *pathname, mode_t mode); int explain_lchmod_on_error(const char *pathname, mode_t mode);

DESCRIPTION

The explain_lchmod_or_die function is used to call the lchmod(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_lchmod(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_lchmod_on_error function is used to call the lchmod(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_lchmod(3) function, but still returns to the caller. pathname The pathname, exactly as to be passed to the lchmod(2) system call. mode The mode, exactly as to be passed to the lchmod(2) system call.

RETURN VALUE

The explain_lchmod_or_die function only returns on success, see lchmod(2) for more infor‐ mation. On failure, prints an explanation and exits, it does not return. The explain_lchmod_on_error function always returns the value return by the wrapped lch‐ mod(2) system call.

EXAMPLE

The explain_lchmod_or_die function is intended to be used in a fashion similar to the fol‐ lowing example: explain_lchmod_or_die(pathname, mode);
