Re: advantage of using typedefs

I wanted to know what advantage do we get by typedefs ? Why we did not
declare
offset simply as
long off_t;

It's often a portability issue. Imagine you want a type that hold the biggest possible unsigned integer.

You will have this in C90:

typedef unsigned long biggest_int_t;

and that on C99:

typedef unsigned long long biggest_int_t;

With the help of some smart macros and #ifxxx directives, After a simple recompile, the type will automagically be corrected after a simple recompile of the project/lib or whatever.
