These functions provide a variety of services for NIS+ applications.
nis_mkdir() 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.3n
nis_rmdir() is used to delete the directory, dirname, from the specified machine. The machine parameter cannot be NULL. For a description of the nis_server structure, refer to nis_objects.3n
nis_servstate()
is used to set and read the various
state variables of the
NIS+
servers.
In particular the internal debugging state
of the servers may 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
nis_servstate() and nis_stats() use the tag list. This 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.
nis_getservlist() 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 structure, refer to nis_objects.3n nis_freeservlist() frees the list of servers returned by nis_getservlist(). Note that this is the only legal way to free that list.
