NAME
gen-ctl-io - generate C interface code for libctl control files
SYNOPSIS
gen-ctl-io [OPTION]... [spec-file]
DESCRIPTION
gen-ctl-io generates C code to import/export the input/output variables
used in a libctl control file. gen-ctl-io generates files like ctl-
io.h and ctl-io.c. These files define global variables, data
structures, and functions for the input/output variables, classes, and
function interfaces defined in the spec-file argument, automating the
interaction between C and Guile.
The arguments such as --code and --header are used to control whether
ctl-io.c or ctl-io.h, etcetera, are generated. If no argument is
specified then both of these files are generated by default, for
backwards compatibility.
libctl is a free library to aid in interfacing scientific software with
the GNU Guile scripting and extension language. Documentation for it
may be found online at the libctl home page: http://ab-
initio.mit.edu/libctl
OPTIONS
--code Generate C (or C++) source code to implement the Guile interface
functions. The default output file name is ctl-io.c (in C) or
ctl-io.cpp (in C++).
--header
Generate the header file declaring the interface data types and
functions. The default output file name is ctl-io.h (in C) or
ctl-io.hpp (in C++).
--swig Generate a SWIG interface definition file declaring automatic
conversions for the various libctl data types. The default
output file name is ctl-io.i.
--cxx Generate C++ code instead of C code.
-o file
Use file as the output file name instead of the defaults
(above).
