MinGW32, LockWorkStation() undefined symbol?

Question

C++ / C#

The problem is the following.
I am developing under Windows 10 , using the MinGW32 compiler and IDE Code::Blocks . I want to use the LockWorkStation() function , but the compiler cannot find the definition of this symbol. Although, if you go through the code editor to this definition, it is located in winuser.h .
According to MSDN , the function I need is in user32.lib . I could not find
such a file in the MinGW compiler directory, so I tried to use user32.lib from other locations, since I have several compilers. It didn't solve the problem.
I tried using the libuser32.a file , which is in the MinGW32 compiler directory , but that didn't help.
I am completely confused. Can you tell me what I need to do in order for MinGW to allow me to use the required function?
