Since Interfaces.C does not supply a "To_Ada" function for
unsigned_char as it does for the other character types, and
you presumably aren't supposed to assume a correlation between
Interfaces.C.char and Interfaces.C.unsigned_char, then you
will have to convert it yourself.

This is assuming you're asking how to convert between 
Interfaces.C.unsigned_char and character, then the simplest
way is probably:

  char : character := ' ';
  uc   : Interfaces.C.unsigned_char := 65;
  
begin

  char := character'val(integer(uc));  -- char is now 'A'


Is this what you were asking?

Frank

Subject: Converting Mod types to Character types...


Hi,
    I've got my interface to Vx thing working but i want to display the
contents
of the information it retrieves.  I've got Interfaces.C.Unsigned_Char types
in
an array and this maps to a Mod type in GNAT.  I've tried allsorts of
conversions between a single C.UC to character and unsigned conversions too.
How do i convert between them?  It's annoying since this is the only thing
that's not working, everything else is.

Thanks,
Chris Campbell
