The information in this article applies to:

Microsoft FoxPro Library Construction Kit for Macintosh, version 2.5b

SUMMARY

All library files compiled with the Macintosh Programmer's Workshop (MPW) compiler must include an example file.

The source code for the library file has an extension of .C. The example file must have the same name as the source code file with the extension changed to .EXP. For example, if the source code is named TEST.C, the example file would be named TEST.EXP.

The following is a description of each section in an example file:

1. The first section contains introductory comments, which are optional and

   can be excluded. Comments are delimited with /* and */.

      /*
         File: MyLibrary.exp
         Contains: Exports file for the Library function set.
         Copyright: (c) 1993 by John Doe, all rights reserved.
      */

2. The second section declares the library. Each .MLB file in the System

   Folder:Extensions subfolder must have a unique library name. If library
   names are not unique, FoxPro will generate an error stating that the
   library file cannot be found. In the example below, the library name is
   MyLibrary. The only text that should be changed is the library name,
   which follows Fox$ on the line beginning with id =.

      Library
            {
            id = "Fox$MyLibrary";
            version = 1.3b6;
            flags = system7;
            heap = application, hold;
         };

3. The next section declares the exported library function set that FoxPro

   recognizes. Enter a valid filename following "API$" on the line
   beginning "id = ". The filename must be in all uppercase (as shown in
   the example below).

      FunctionSet Testlib
         {
            id = "Fox:API$MYLIBRARY.MLB, 1.3";
            version = 1.0...1.3b6;
            exports = extern pascal DispatchAPI;
         };

    *** End Of File

When the source code file is compiled, it should be given the same name as stated in the FunctionSet. In this example, the compiled file would be named MYLIBRARY.MLB.

MORE INFORMATION

During installation, a sample .EXP file is copied onto the hard drive. The filename is TEST.EXP and it is located in the Examples subfolder of the FoxLCK folder.
