查帮助就行了。基本上是函数调用的参数约定，<br>The register and pascal conventions pass parameters from left to right; that is, the left most parameter is evaluated and passed first and the rightmost parameter is evaluated and passed last. The cdecl, stdcall, and safecall conventions pass parameters from right to left.<br> For all conventions except cdecl, the procedure or function removes parameters from the stack upon returning. With the cdecl convention, the caller removes parameters from the stack when the call returns.<br><br>The register convention uses up to three CPU registers to pass parameters, while the other conventions pass all parameters on the stack.<br> The safecall convention implements exception "firewalls." On Windows, this implements interprocess COM error notification.
