explain_pathconf_or_die - get configuration values and report errors
#include <libexplain/pathconf.h>
long explain_pathconf_or_die(const char *pathname, int name);
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.
- pathconf(3)
- get configuration values for files
- explain_pathconf(3)
- explain pathconf(3) errors
- exit(2)
- terminate the calling process
