.SH DESCRIPTION
.sp
.LP
The \fBptree_update_propval()\fR function updates the value of the property specified by \fIproph\fR with the value specified in the buffer \fIvalbuf\fR. The size of the buffer \fIvalbuf\fR is specified in \fInbytes\fR.
.sp
.LP
The \fBptree_update_propval_by_name()\fR function updates the value of the property, whose name is specified by \fIname\fR, of the node specified by handle \fInodeh\fR.  The new value is specified in the buffer \fIvalbuf\fR, whose size is specified in \fInbytes\fR.
.sp
.LP
For volatile properties, the write access function provided by the plug-in publishing the property is invoked.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fB0\fR is returned. On failure, a non-negative integer is returned to indicate an error.
.sp
.LP
\fBPICL_STALEHANDLE\fR is returned if the handle is no longer valid. This occurs if the PICL tree was refreshed or reinitialized.
.sp
.LP
\fBPICL_INVALIDHANDLE\fR is returned if the specified handle never existed.
