GetMsgProc info  Overview  Group

The GetMsgProc hook procedure is an application-defined or library-defined callback function that the system calls whenever the GetMessage function has retrieved a message from an application message queue. Before passing the retrieved message to the destination window procedure, the system passes the message to the hook procedure.

LRESULT CALLBACK GetMsgProc(

    int code,

// hook code

    WPARAM wParam,

// removal flag

    LPARAM lParam 

// address of structure with message

   );

Parameters

code
Specifies whether the hook procedure must process the message. If code is HC_ACTION, the hook procedure must process the message. If code is less than zero, the hook procedure must pass the message to the CallNextHookEx function without further processing and should return the value returned by CallNextHookEx.
wParam
Specifies whether the message has been removed from the queue. This parameter can be one of the following values:

Value

Meaning

PM_NOREMOVE

Specifies that the message has not been removed from the queue. (An application called the PeekMessage function, specifying the PM_NOREMOVE flag.)

PM_REMOVE

Specifies that the message has been removed from the queue. (An application called GetMessage, or it called the PeekMessage function, specifying the PM_REMOVE flag.)

lParam
Points to an MSG structure that contains details about the message.

Return Values

The return value should be zero.

Remarks

The GetMsgProc hook procedure can examine or modify the message. After the hook procedure returns control to the system, the GetMessage function returns the message, along with any modifications, to the application that originally called it.

An application installs this hook procedure by specifying the WH_GETMESSAGE hook type and the address of the hook procedure in a call to the SetWindowsHookEx function.

GetMsgProc is a placeholder for the application-defined or library-defined function name.
