Create Pascal header file from C header (include) files

There are about 20 C header files (see attachment) of a C library which I want to use in a Pascal project. The job is to create a .pas header file -- create a file named [login to view URL] and place in it all the types and constants and function calls from all the C header files. Please note: 1. The C header files are in the attachment. 2. The resulting Pas file is to be used by Free Pascal Compiler, not Delphi. So it must compile with FPC. 3. The source code for this job comes from this open source project: [login to view URL] (pre-nougat version) 4. All the *.h units included in "[login to view URL]" should be converted. The list should be like this: fluidsynth.h #include "fluidsynth/types.h" #include "fluidsynth/settings.h" #include "fluidsynth/synth.h" #include "fluidsynth/shell.h" #include "fluidsynth/sfont.h" #include "fluidsynth/ramsfont.h" #include "fluidsynth/audio.h" #include "fluidsynth/event.h" #include "fluidsynth/midi.h" #include "fluidsynth/seq.h" #include "fluidsynth/seqbind.h" #include "fluidsynth/log.h" #include "fluidsynth/misc.h" #include "fluidsynth/mod.h" #include "fluidsynth/gen.h" #include "fluidsynth/voice.h" #include "fluidsynth/version.h"
