SYNOPSIS

#include <libexplain/lchown.h>
void explain_lchown_or_die(const char *pathname, int owner, int group);

DESCRIPTION

The explain_lchown_or_die function is used to call the lchown(2) system call. On failure an explanation will be printed to stderr, obtained from explain_lchown(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_lchown_or_die(pathname, owner, group);

pathname

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

	owner		The owner, exactly as to be passed to the lchown(2) system call.
	group		The group, exactly as to be passed to the lchown(2) system call.

Returns:

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