- Interfacing Amiga Basic Programs with FutureSound sounds
- --------------------------------------------------------
-
- The Amiga Basic program 'Example' is an example of using FutureSound
- sampled sound files in an Amiga Basic program.
-
- The keys to the interface between the FutureSound routines and Amiga
- Basic are the files 'future.library', 'future.bmap' and 'exec.bmap'.
-
- These files must be present when your program is executed. They can
- be in the same directory (or drawer) where you run your Amiga Basic
- programs.
-
- If you are using FutureSound files in your Amiga Basic programs
- alot, then copy the 'future.library' file to the LIBS: directory.
- This directory is called 'libs' on your Workbench disk.
-
- In the CLI, type:
-
- COPY DF1:BasicDemos/future.library LIBS:
-
- Depending on your system set-up, this command may be different.
-
- Both '.bmap' files must be present in the directory where you are
- running you Amiga Basic program. The '.bmap' files coordinate
- the interface between Amiga Basic and the 'future.library'.
-
- The source code to Example is included at the end of this text.
- It is nearly self-documenting. :-)
-
-
- 'future.library' Example AmigaDOS library
-
- 'future.library' is an AmigaDOS library composed of some interface
- assembly language code, and the FutureSound C routines supplied
- on this disk.
-
- The complete source to the 'future.library' is included. If you
- have the Metacomco assembler and the Lattice C compiler, you can
- modify the 'future.library' to suit your needs.
-
- The example Lattice C functions were converted to use only AmigaDOS
- level input and output, i.e., 'Open()' instead of 'fopen()'.
-
- Also, all references to 'stdin' and 'stdout' I/O were removed.
- The functions were compiled with stack checking off, using the '-v'
- option in the 'lc2' pass of the compiler.
-
- Also, the Lattice 'strcmp()' function was replaced with an equivalent
- function.
-
- The functions were linked only with 'amiga.lib', not 'lc.lib'.
-
- The functions do not need any startup code. '_DOSBase' and '_SysBase'
- were resolved in the 'future.asm' code, the core of the library.
- These were the only unresolved references. The 'future.asm' file
- contains more details of the interface between C and assembler.
-
- These changes produce nearly stand-alone C functions, a necessity
- for inclusion in an AmigaDOS library.
-
- Example assemble, compile and link files are included.
