error C2011 tagPOINT struct type redefinition

This error occurs when you try to redefine a struct type that has already been defined elsewhere in the code.

To fix this error, you can either remove the redundant definition or use an include guard to prevent multiple definitions of the same struct type.

An include guard is a preprocessor directive that ensures that a header file is only included once in your code. You can add an include guard to your header file by wrapping the entire content of the file in a #ifndef/#define/#endif block. For example:

#ifndef MY_HEADER_FILE_H #define MY_HEADER_FILE_H

// Struct definition and other code here

#endif // MY_HEADER_FILE_
