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.
