The RM95 B.3.1 contains: "The type chars_ptr is C-compatible and
corresponds to the use of C's ``char *'' for a pointer to the first char
in a char array terminated by nul.".
Doesn't it imply that it has a C convention, or at least that it can be
converted to an access type with convention C without warranting a
warning? When compiling the following test with GCC trunk and -Wall, I get:
t.ads:10:04: warning: conversion between pointers with different conventions
(I know the following code looks strange, but it is a specially built
test case following a more complex case found in AdaSockets)
--
with Ada.Unchecked_Conversion;
with Interfaces.C.Strings;
package T is
type P is access Integer;
pragma Convention (C, P);
function Convert is
new Ada.Unchecked_Conversion (Interfaces.C.Strings.chars_ptr, P);
end T;
