.SH NAME
yp_update \- change NIS information
.SH SYNOPSIS

#include <rpcsvc/ypclnt.h>



\fBint\fR \fByp_update\fR(\fBchar *\fR\fIdomain\fR, \fBchar *\fR\fImap\fR, \fBunsigned\fR \fIypop\fR, \fBchar *\fR\fIkey\fR,

.SH DESCRIPTION
.sp
.LP
\fByp_update()\fR is used to make changes to the NIS database. The syntax is
the same as that of \fByp_match()\fR except for the extra parameter \fIypop\fR
which may take on one of four values. If it is \fBPOP_CHANGE\fR then the data
associated with the key will be changed to the new value. If the key is not
found in the database, then \fByp_update()\fR will return \fBYPERR_KEY\fR. If
\fIypop\fR has the value \fBYPOP_INSERT\fR then the key-value pair will be
inserted into the database. The error \fBYPERR_KEY\fR is returned if the key
already exists in the database. To store an item into the database without
concern for whether it exists already or not, pass \fIypop\fR as
\fBYPOP_STORE\fR and no error will be returned if the key already or does not
exist. To delete an entry, the value of \fIypop\fR should be \fBYPOP_DELETE\fR.
.sp
.LP
This routine depends upon secure \fBRPC,\fR and will not work unless the
network is running secure \fBRPC.\fR
.SH RETURN VALUES
.sp
.LP
If the value of  \fIypop\fR is  \fBPOP_CHANGE,\fR \fByp_update()\fR returns the
error \fBYPERR_KEY\fR if the key is not found in the database.
.sp
.LP
If the value of  \fIypop\fR is  \fBPOP_INSERT,\fR \fByp_update()\fR returns the
error \fBYPERR_KEY\fR if the key already exists in the database.
