Summary

The pragma Import directs the compiler to use code or data objects written in a foreign computer language.

Which foreign languages are supported depends on the compiler implementation. Typically C, C++, Cobol, and Fortran are supported.

Example

/* C file */
int my_C_function() {
  return 1;
}

-- Ada File
function My_C_Function return Integer;
pragma Import
  (Convention    => C,
   Entity        => My_C_Function,
   External_Name => "my_C_function" );
...
Some_Variable := My_C_Function; -- Ada uses a foreign language like a pro!
                                -- Huzzah!
