Calling Ada from C

[Maxwelton <maxwelton@my-deja.com>]

I am missing something in a program I am working on. I am using a C
function to call a function in Ada.  I have the function defined in
a ".h" file as an "extern". It takes a string as a parameter. In Ada I
have a function with the same name defined along with the export pragma
in the .ads file. The C function name is the 3rd parameter. If I were
calling "C" from Ada I would use the import pragma. The .adb file has
the function containing
       procedure To_Ada (Item     : in char_array;
                         Target   : out String;
                         Count    : out Natural;
                         Trim_Nul : in Boolean := True);

I am using the Interfaces.C package in my ada files. My files compile
but the C compilation generates an error that states "undefined
function". What am I not doing?
