CreateMutex () Parameter problem

Example: Hmutex = CreateMutex (NULL, FALSE, "screen");

Error C2664: "CREATEMUTEXW": Cannot convert parameter 3 from "const char [7]" to "LPCWSTR"

Not related to the type that is pointed to, conversion requires reinterpret_cast, C-style conversion, or function-style conversion;

Workaround: The ASCII environment calls the Createmutexa,unciode environment call CREATEMUTEXW

The reason for this example is that the Unicode environment is used, the function automatically calls the CREATEMUTEXW wide character function, so the parameter LPCTSTR is LPCWSTR type, plus _t (), TEXT (), or L (character) Hmutex = CreateMutex (NULL, false,_t ("screen")), or Hmutex = CreateMutex (null, false,l "screen"); or Hmutex = CreateMutex (NULL, False,text ("screen"));
