These functions provide a variety of services for NIS+ applications.

The nis_mkdir() function is used to create the necessary databases to support NIS+ service for a directory, dirname, on a server, machine. If this operation is successful, it means that the directory object describing dirname has been updated to reflect that server machine is serving the named directory. For a description of the nis_server structure, refer to nis_objects(3NSL).

Per-server and per-directory access restrictions can apply to the nis_mkdir() function. See nisopaccess(1).

The nis_rmdir() function is used to delete the directory, dirname, from the specified server machine. The machine parameter cannot be NULL. The nis_rmdir() function does not remove the directory dirname from the namespace or remove a server from the server list in the directory object. To remove a directory from the namespace you must call nis_remove() to remove the directory dirname from the namespace and call thenis_rmdir() for each server in the server list to remove the directory from the server. To remove a replica from the server list, you need to first call nis_modify() to remove the server from the directory object and then call nis_rmdir() to remove the replica.

Per-server and per-directory access restrictions can apply to nis_rmdir(). See nisopaccess(1).

For a description of the nis_server structure, refer to nis_objects(3NSL).

The nis_servstate() function is used to set and read the various state variables of the NIS+ servers. In particular the internal debugging state of the servers can be set and queried.

The nis_stats() function is used to retrieve statistics about how the server is operating. Tracking these statistics can help administrators determine when they need to add additional replicas or to break up a domain into two or more subdomains. For more information on reading statistics, see nisstat(1M).

The nis_servstate() and nis_stats() functions use the tag list. The tag list is a variable length array of nis_tag structures whose length is passed to the function in the numtags parameter. The set of legal tags are defined in the file <rpcsvc/nis_tags.h> which is included in <rpcsvc/nis.h>. Because these tags can and do vary between implementations of the NIS+ service, it is best to consult this file for the supported list. Passing unrecognized tags to a server will result in their tag_value member being set to the string unknown. Both of these functions return their results in malloced tag structure, *result. If there is an error, *result is set to NULL. The tag_value pointers points to allocated string memory which contains the results. Use nis_freetags() to free the tag structure.

Per-server and per-directory access restrictions can apply to the NIS_SERVSTATE or NIS_STATUS (nis_stats()) operations and their sub-operations (tags). See nisopaccess(1).

The nis_getservlist() function returns a null terminated list of nis_server structures that represent the list of servers that serve the domain named dirname. Servers from this list can be used when calling functions that require the name of a NIS+ server. For a description of the nis_server refer to nis_objects(3NSL). nis_freeservlist() frees the list of servers list of servers returned by nis_getservlist(). Note that this is the only legal way to free that list.

NIS+ might not be supported in future releases of the Solaris operating system. Tools to aid the migration from NIS+ to LDAP are available in the current Solaris release. For more information, visit
