检查winapi功能是否可用

Question

Is is possible in c++ to check if a function is available? For example SetThreadPriority . If it is available, I want to call it, if not I want to simply ignore it, as it is not critical for my application.

Answer 1

You can use the GetProcAddress function. The example in the link does exactly this kind of thing: it checks if the GetNativeSystemInfo is available and calls it if yes, otherwise it calls the GetSystemInfo function.

Answer 2

May be you are looking for Dynamic Linking Function . If so, then use LoadLibraryEx then GetProcAddress

This will allow you skip the DLL load if it is not available
