XMADDPROTOCOLCALLBACK(3)

✨ XmAddProtocolCallback ✨

okay bestie, we're in the library call section of the manual and this one is a VendorShell function, so buckle up 🎀

💖 NAME 💖

XmAddProtocolCallback — a VendorShell function that adds client callbacks for a protocol. that's it, that's the whole job, and she does it flawlessly 💅

🌸 SYNOPSIS 🌸

#include <Xm/Protocols.h>
void XmAddProtocolCallback(
Widget shell,
Atom property,
Atom protocol,
XtCallbackProc callback,
XtPointer closure);

🦋 DESCRIPTION 🦋

so like, XmAddProtocolCallback adds client callbacks for a protocol. she first does a vibe check on whether the protocol is registered — and if it is not, she calls XmAddProtocols for you (she's got you, don't worry 🫶). then she adds the callback to the internal list. these callbacks get called when the corresponding client message is received. iconic behavior, no cap ✨

XmAddWMProtocolCallback is a convenience interface, i.e. the low-effort bestie version. it calls XmAddProtocolCallback with the property value set to the atom returned by interning WM_PROTOCOLS. periodt.

now the arguments, one by one, because we respect her 🌈

• shell — specifies the widget with which the protocol property is associated 💜
• property — specifies the protocol property 🎀
• protocol — specifies the protocol Atom ⭐
• callback — specifies the procedure to call when a protocol message is received 🔥
• closure — specifies the client data to be passed to the callback when it is invoked 🍓
