Could anyone please tell me how to do API calls from user32 and kernel32?

Like this
Extern "Win32"
	Function GetCurrentProcess:Int()
	Function ReadProcessMemory:Int(hProcess:Int,lpBaseAddress:Byte Ptr,lpBuffer:Byte Ptr,nSize:Int,lpNumberOfBytesRead:Byte Ptr)
	Function WriteProcessMemory:Int(hProcess:Int,lpBaseAddress:Byte Ptr,lpBuffer:Byte Ptr,nSize:Int,lpNumberOfBytesWritten:Byte Ptr)
EndExtern

Does using "Win32" as the head open user32.dll,kernel32.dll, and gdi32.dll?

it will link it against the own kernel32.a etc in the lib folder. with 1.26+ and mingw 5.1 this should cover more or less all XP API capabilities, yes.

"Win32" is the stdcall calling convention, your source code gets linked with user32 and kernel32 anyway.
If you want to link an import library in the lib folder use "import -l" followed by the name. If you rather load a dll at run-time use the GetProcAddress API.
