@trusted string sysErrorString(DWORD errCode, int langId = LANG_NEUTRAL, int subLangId = SUBLANG_DEFAULT);

Query the text for a Windows error code, as returned by GetLastError, as a D string.

class WindowsException: object.Exception;

Thrown if errors that set GetLastError occur.

final @property DWORD code();

GetLastError's return value.

@safe T wenforce(T, S)(T value, lazy S msg = null, string file = __FILE__, size_t line = __LINE__)
Constraints: if (isSomeString!S);

If !!value is true, value is returned. Otherwise, new WindowsException(GetLastError(), msg) is thrown. WindowsException assumes that the last operation set GetLastError() appropriately.

Example

wenforce(DeleteFileA("junk.tmp"), "DeleteFile failed");
