NAME

explain_pathconf_or_die - get configuration values and report errors

SYNOPSIS

#include <libexplain/pathconf.h>

long explain_pathconf_or_die(const char *pathname, int name);

DESCRIPTION

The explain_pathconf_or_die function is used to call the pathconf(3) system call. On failure an explanation will be printed to stderr, obtained from explain_pathconf(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:

long value = explain_pathconf_or_die(pathname, name);

Note that a -1 return value is still possible, meaning the system does not have a limit for the requested resource.

pathname

The pathname, exactly as to be passed to the pathconf(3) system call.

name

The name, exactly as to be passed to the pathconf(3) system call.

Returns:

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

SEE ALSO

exit(2)
