DispatchMessage 函数

调试一个消息给窗口过程。典型的用法是调度被 GetMessage 返回的消息。
 函数原型:
 LRESULT WINAPI DispatchMessage ( MSG * lpmsg  );
参数
lpmsg
类型:MSG *
指向一个 MSG 结构体指针。
返回值
类型:LRESULT
返回值标识被窗口过程返回的值。由于意义取决于被调度的消息,通常返回值会被忽略。
备注
MSG 结构体必须包含可用信息。如果lpmsg指向的是 WM_TIMER ,lParam不为NULL,DispatchMessage将会调用lParam指向的函数,而不是窗口过程。
支持
最低桌面系统支持Windows 2000 Professional
头文件Winuser.h (已包含在Windows.h中)
User32.lib
DLLUser32.dll
UNICODE版本名DispatchMessageW
ANSI版本名DispatchMessageA
