Learn to determine whether a Windows API function requires .bss or .data section by analyzing its parameters and documentation
Action Steps
- Read the Windows API documentation for the function you're interested in
- Identify the parameters marked as [in] or [in, optional] and check if they require a pointer to a buffer or a structure
- If a parameter requires a pointer to a buffer, check if the buffer needs to be initialized before the function call
- Use the .data section for initialized data and the .bss section for uninitialized data
- Test your assembly code to ensure correct functionality and section usage

Im learning assembly and im trying to ween myself off of claude. I understand stack alignment and pushing and popping etc. However im not sure how to know when a particular windows api call needs .bss or data section. For example ill find a func in the windows docs like HANDLE CreateFileA( [in] LPCSTR lpFileName, [in] DWORD dwDesiredAccess, [in] DWORD dwShareMode, [in, optional] LPSECURITY_ATTRIBUTES lpSecurityAttributes, [i
