Certainly, although we call them "abstract data types".  ADT is a
trademark of a security firm (American District Telegraph).

You can implement abstract data types in almost any programming
language.  Ada has facilities for forcing you to use them, and
C++ has special support for them.

The usual access to an abstract data type in a C application is
via a header file that defines the data type(s) and declares the
functions used to implement it.  The functions are implemented in
a separate source file with everything except the header-documented
access hooks made file-static.
