reading/writing a file without any header file

i need to read/write to a text/binary file without using any header file in c.
i cant use the FILE strucutire as it is defined in stdio.h nor can i use file input/output functions as they are defined in fstream.header file???i think that i need to define my own functions for file i/o...how??

Please read the posting guidelines.

This looks like an academic exercise. Otherwise, this is a waste of time.

The only other choice I think of are the system level routines for IO. These are the calls used by other mechanisms, like FILE*, but they are accessed through header files.

Remember, this is a C/C++ forum and in these languages, you gain access to the operating system through the header files and associated libraries.
