上述代码定义了一个名为Callback的回调函数类型,该回调函数接受一个int类型的参数,并且没有返回值。然后,通过process函数将一个回调函数作为参数传递进去。 腾讯云提供了丰富的云计算产品,其中与函数声明相关的产品包括云函数(Serverless Cloud Function)和函数计算(Serverless Cloud Run)。云函数是一种无需管理服务...

1、CControlUI* (CALLBACK* FINDCONTROLPROC)(CControlUI*, LPVOID),是个指向函数的指针,其中:返回值为CControlUI的指针,参数列表为CControlUI的指针,LPVOID类型变量。2,typedef之后,可以使用重命名的指针函数类型FINDCONTROLPROC来定义只想此类函数的指针变量,比如:// 已经存在这样一个函数 C...
