NAME

6       gen-ctl-io - generate C interface code for libctl control files
7

SYNOPSIS

9       gen-ctl-io [OPTION]... [spec-file]
10

DESCRIPTION

12       gen-ctl-io generates C code to import/export the input/output variables
13       used in a libctl control file.  gen-ctl-io generates  files  like  ctl-
14       io.h  and  ctl-io.c.   These files define global variables, data struc‐
15       tures, and functions for the input/output variables, classes, and func‐
16       tion  interfaces  defined  in  the  spec-file  argument, automating the
17       interaction between C and Guile.
18
19       The arguments such as --code and --header are used to  control  whether
20       ctl-io.c or ctl-io.h, etcetera, are generated.  If no argument is spec‐
21       ified then both of these files are generated by default, for  backwards
22       compatibility.
23
24       libctl is a free library to aid in interfacing scientific software with
25       the GNU Guile scripting and extension language.  Documentation  for  it
26       may   be   found   online  at  the  libctl  home  page:  http://ab-ini‐
27       tio.mit.edu/libctl

OPTIONS

30       --code Generate C (or C++) source code to implement the Guile interface
31              functions.   The  default output file name is ctl-io.c (in C) or
32              ctl-io.cpp (in C++).
33
34       --header
35              Generate the header file declaring the interface data types  and
36              functions.  The  default  output file name is ctl-io.h (in C) or
37              ctl-io.hpp (in C++).
38
39       --swig Generate a SWIG interface definition  file  declaring  automatic
40              conversions for the various libctl data types.  The default out‐
41              put file name is ctl-io.i.
42
43       --cxx  Generate C++ code instead of C code.
44
45       -o file
46              Use file as  the  output  file  name  instead  of  the  defaults
47              (above).
