Pragma Interface


     pragma Interface (
          [Convention    =>] convention_identifier,
          [Entity        =>] local_NAME
       [, [External_Name =>] static_string_expression]
       [, [Link_Name     =>] static_string_expression]);

This pragma is identical in syntax and semantics to the standard Ada pragma Import. It is provided for compatibility with Ada 83. The definition is upwards compatible both with pragma Interface as defined in the Ada 83 Reference Manual, and also with some extended implementations of this pragma in certain Ada 83 implementations. The only difference between pragma Interface and pragma Import is that there is special circuitry to allow both pragmas to appear for the same subprogram entity (normally it is illegal to have multiple Import pragmas. This is useful in maintaining Ada 83/Ada 95 compatibility and is compatible with other Ada 83 compilers.
