2.80 Pragma Import_Procedure ¶

Syntax:

pragma Import_Procedure (
     [Internal                 =>] LOCAL_NAME
  [, [External                 =>] EXTERNAL_SYMBOL]
  [, [Parameter_Types          =>] PARAMETER_TYPES]
  [, [Mechanism                =>] MECHANISM]);

EXTERNAL_SYMBOL ::=
  IDENTIFIER
| static_string_EXPRESSION

PARAMETER_TYPES ::=
  null
| TYPE_DESIGNATOR {, TYPE_DESIGNATOR}

TYPE_DESIGNATOR ::=
  subtype_NAME
| subtype_Name ' Access

MECHANISM ::=
  MECHANISM_NAME
| (MECHANISM_ASSOCIATION {, MECHANISM_ASSOCIATION})

MECHANISM_ASSOCIATION ::=

This pragma is identical to Import_Function except that it applies to a procedure rather than a function and the parameters Result_Type and Result_Mechanism are not permitted.
