NAME
       ypupdate: yp_update() - changes NIS information

SYNOPSIS
       [flag]... file... [library]...

   Remarks
       The  Network  Information  Service  (NIS) was formerly known as Yellow Pages (YP).  Although the name has changed, the functionality of the
       service remains the same.

DESCRIPTION
       The routine is used to make changes to the Network Information Service (NIS) database.  The syntax is the same as that of (see  ypclnt(3C))
       except for the extra parameter which can be one of these four values:

	      The data associated with the key will be changed to the new value.
				  If the key is not found in the database, then returns

	      The key-value pair will be inserted into the database.
				  The error is returned if the key already exists in the database.

	      The key-value pair will be stored into the database without concern for whether
				  it already exists or not.

	      The key-value pair will be deleted from the database.

       This routine depends upon secure RPC and will not work unless the network is running secure RPC.

MULTITHREAD USAGE
       Thread Safe:	     No
       Cancel Safe:	     No
       Fork Safe:	     No
       Async-cancel Safe:    No
       Async-signal Safe:    No

       These  functions  cannot be called safely in a multithreaded environment.  They may be cancellation points in that they call functions that
       are cancel points.

       In a multithreaded environment, these functions are not safe to be called by a child process after and before These functions should not be
       called by a multithreaded application that support asynchronous cancellation or asynchronous signals.
