Name

nis_local_names, nis_local_directory, nis_local_host, nis_local_group, nis_local_principal– NIS+ local names

Synopsis

cc [ flag ... ] file ... -lnsl [ library ... ]
#include <rpcsvc/nis.h>



nis_name nis_local_directory(void);

nis_name nis_local_host(void);

nis_name nis_local_group(void);

nis_name nis_local_principal(void);

Description

These functions return several default NIS+ names associated with the current process.

nis_local_directory() returns the name of the NIS+ domain for this machine. This is currently the same as the Secure RPC domain returned by the sysinfo(2) system call.

nis_local_host() returns the NIS+ name of the current machine. This is the fully qualified name for the host and is either the value returned by the gethostname(3C) function or, if the host name is only partially qualified, the concatenation of that value and the name of the NIS+ directory. Note that if a machine's name and address cannot be found in the local NIS+ directory, its hostname must be fully qualified.

nis_local_group() returns the name of the current NIS+ group name. This is currently set by setting the environment variable NIS_GROUP to the groupname.

nis_local_principal() returns the NIS+ principal name for the user associated with the effective UID of the calling process. This function maps the effective uid into a principal name by looking for a LOCAL type credential in the table named cred.org_dir in the default domain. See nisaddcred(1M).

The result returned by these routines is a pointer to a data structure with the NIS+ library, and should be considered a “read-only” result and should not be modified.

Environment Variables

NIS_GROUP

This variable contains the name of the local NIS+ group. If the name is not fully qualified, the value returned by nis_local_directory() will be concatenated to it.

Attributes
