Library for Cross platform datatypes in C
===

Is there a C (not C++, Boost etc.) library for providing cross platform datatypes ? 

To elaborate, I want to store an int in a file in a 32-bit linux machine, read the file and the same int from a 64-bit windows machine. Is this possible ?

Update: I do not want to use sqlite or some kind of database either. I want a library which can help me in using the datatypes throughout my code.
