The PICL class name of the visited node is compared with the class name specified by \fIclassname\fR. If the class names match, the callback function specified by \fIcallback\fR is called with the matching node handle and the argument provided in \fIc_args\fR. If the class name specified in \fIclassname\fR is \fINULL\fR, then the callback function is invoked for all the nodes. .sp .LP The return value from the callback function is used to determine whether to continue or terminate the tree walk. The callback function returns \fBPICL_WALK_CONTINUE\fR or \fBPICL_WALK_TERMINATE\fR to continue or terminate the tree walk. .SH RETURN VALUES .sp .LP Upon successful completion, \fB0\fR is returned. On failure, a non-negative integer is returned to indicate an error. .SH ERRORS .sp .ne 2 .na \fB\fBPICL_NOTNODE\fR\fR .ad .RS 22n Not a node .RE .sp .ne 2 .na \fB\fBPICL_INVALIDHANDLE\fR\fR .ad .RS 22n Invalid handle specified .RE .sp .ne 2 .na \fB\fBPICL_STALEHANDLE\fR\fR .ad .RS 22n Stale handle specified .RE .sp .ne 2 .na \fB\fBPICL_FAILURE\fR\fR .ad .RS 22n General system failure .RE .SH ATTRIBUTES .sp .LP See \fBattributes\fR(7) for descriptions of the following attributes: .sp .sp .TS box; c | c l | l .
