条件变量函数未在此范围内声明

Question

Its the first time I'm using WINAPI and with functions like SleepConditionVariableCS , WakeConditionVariable , WaitForMultipleObjects and InitializeConditionVariable Eclipse IDE told me that they were not declared in this scope.

All of them are supposedly included in the same lib windows.h so i dont know what's failings because other functions like ExitThread , ReleaseSemaphore and WaitForSingleObject are running without any problem.

It can be some problem with my c++ version? Or it exist any other library to include?

Thanks

Answer 1

The documentation for SleepConditionVariableCS (or any other WIndows API call) tells you the minimum supported client and server OS. The API calls are conditionally declared, based on your target platform setting.

You can control your target platform by setting certain preprocessor macros (see Using the Windows Headers for information). In your case you need to add

#define WINVER 0x0600

before including Windows.h , to target Windows Vista and later. It is common practice to define the preprocessor macro on the command line, to use a consistent environment across all compilation units.
