Description

A C program consists of one or more translation units, each of which can be compiled separately. A translation unit consists of a source file together with any headers and source files included by the #include preprocessing directive. Each time the compiler is invoked, it reads a single translation unit and typically produces a relocatable object file. A translation unit must contain at least one declaration or function definition.
