.SH "SYNOPSIS"

.PP

.nf

#include <Xm/Protocols\&.h>

\fBvoid \fBXmAddProtocolCallback\fP\fR(

\fBWidget \fBshell\fR\fR,

.SH "DESCRIPTION"

.PP

\fBXmAddProtocolCallback\fP adds client callbacks for a protocol\&. It

checks if the protocol is registered, and if it is not,

calls \fBXmAddProtocols\fP\&. It then adds the callback to

the internal list\&. These callbacks are called when

the corresponding client message is received\&.

.PP

\fBXmAddWMProtocolCallback\fP is a convenience interface\&.

It calls \fBXmAddProtocolCallback\fP

with the property value set to the atom returned by

interning \fBWM_PROTOCOLS\fP\&.

.IP "\fIshell\fP" 10

Specifies the widget with which the protocol property is associated

.IP "\fIproperty\fP" 10

Specifies the protocol property

.IP "\fIprotocol\fP" 10

Specifies the protocol \fBAtom\fP

.IP "\fIcallback\fP" 10

Specifies the procedure to call when a protocol message is received

.IP "\fIclosure\fP" 10

Specifies the client data to be passed to the callback when it is invoked
