.SH DESCRIPTION
.sp
.LP
The \fBptree_get_propval()\fR function gets the value of the property specified by the handle \fIproph\fR and copies it into the buffer specified by \fIvalbuf\fR.  The size of the buffer \fIvalbuf\fR is specifed in \fInbytes\fR.
.sp
.LP
The \fBptree_get_propval_by_name()\fR function gets the value of the property, whose name is specified by \fIname\fR, from the node specified by handle \fInodeh\fR.  The value is copied into the buffer specified by \fIvalbuf\fR. The size of the buffer is specified by \fInbytes\fR.
.sp
.LP
For volatile properties, the read 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\fBPICL_STALEHANDLE\fR is returned if the handle is no longer valid.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.
