       glib-genmarshal - generates C code marshallers for GLib closures

       glib-genmarshal [--body] [--g-fatal-warnings] [--header] [--help] [--internal] [--nostdinc
       | --stdinc] [--prefix=dir] [--skip-source] [--version] [file...]

       glib-genmarshal generates C code marshallers for callback functions of the GClosure mecha-
       nism  in  the  GObject sublibrary of GLib. The marshaller functions have a standard signa-
       ture. The following are passed to the marshaller functions: the invoking closure, an array
       of  value  structures  holding the callback function parameters, and a value structure for
       the return value of the callback. The marshaller then calls the C  code	function  of  the
       closure with all of the parameters on the stack, and collects the return value.

       glib-genmarshal	generates  the	specified  list  of  marshallers.  The marshaller list is
       either read from standard input or from files passed as additional arguments on	the  com-
       mand line.

       The  marshaller lists are processed line by line. A line can contain a comment in the fol-
       lowing format:

       # this is a comment

       A marshaller list can contain a marshaller specification in the following format:

       # up to 16 PTYPEs may be present

       RTYPE specifies the callback return type. PTYPE specifies  the  callback  parameter  list,
       except for the first and the last arguments which are always pointers.

   Parameter Types
       Currently, the following parameter types are supported:

       BOOL		       Deprecated alias for BOOLEAN.

       BOOLEAN		       Boolean type (gboolean).

       BOXED		       Boxed, anonymous but reference counted, type (GBoxed*).

       CHAR		       Signed char type (gchar).

       DOUBLE		       Double-precision float type (gdouble).

       ENUM		       Enumeration type (gint).

       FLAGS		       Flag enumeration type (guint).

       FLOAT		       Single-precision float type (gfloat).

       INT		       Signed integer type (gint).

       INT64		       Signed 64bit integer type (gint64).

       LONG		       Signed long integer type (glong).

       NONE		       Deprecated alias for VOID.

       OBJECT		       GObject or derived type (GObject*).

       PARAM		       GParamSpec or derived type (GParamSpec*).

       POINTER		       Anonymous pointer type (gpointer).

       STRING		       String type (gchar*).

       UCHAR		       Unsigned char type (guchar).

       UINT		       Unsigned integer type (guint).

       UINT64		       Unsigned 64bit integer type (guint64).

       ULONG		       Unsigned long integer type (gulong).

       VOID		       No  return  type,  or  no extra parameters. If VOID is used as the
			       parameter list, no additional parameters may be present.

       The following options are supported:

       --body		       Generate the C code file contents of the marshallers.

       --g-fatal-warnings      Make warnings fatal, that is,  exit  immediately  once  a  warning

       --internal	       Mark  generated functions as internal by using the G_GNUC_INTERNAL

       --header 	       Generate the header file contents of the marshallers.

       -h, --help	       Show usage and basic help information.

       --nostdinc	       Do not use the standard marshallers of the GObject  library,   and
			       skip the gmarshal.h include directive in generated header files.

       --stdinc 	       Use  the  standard marshallers of the GObject library, and use the
			       gmarshal.h include directive in generated header files.

       --prefix=dir	       Specify the marshaller  prefix.	The  default  prefix  is  g_cclo-

       --skip-source	       Skip source location remarks in generated comments.

       -v, --version	       Show version information.

       The following operands are supported:

       file		       Specifies the marshaller to be generated.

       Example 1: Generating Marshallers

       This example shows how to generate marshallers for the following callback functions:

       void	foo (gpointer data1,
		     gpointer data2);
       void	bar (gpointer data1,
		     gint param1,
		     gpointer data2);
       gfloat	baz (gpointer data1,
		     gboolean param1,
		     guchar param2,
		     gpointer data2);

       The marshaller list is as follows:


       The generated marshallers have the arguments encoded in their function name. For this par-
       ticular list, they are as follows:


       The generated marshallers can be used directly for GClosures or can be passed  in  as  the
       GSignalCMarshaller c_marshaller; argument upon creation of signals:

       GClosure *cc_foo, *cc_bar, *cc_baz;

       cc_foo = g_cclosure_new (NULL, foo, NULL);
       g_closure_set_marshal (cc_foo, g_cclosure_marshal_VOID__VOID);
       cc_bar = g_cclosure_new (NULL, bar, NULL);
       g_closure_set_marshal (cc_bar, g_cclosure_marshal_VOID__INT);
       cc_baz = g_cclosure_new (NULL, baz, NULL);
       g_closure_set_marshal (cc_baz, g_cclosure_marshal_FLOAT__BOOLEAN_UCHAR);

       The following exit values are returned:

       0	Application exited successfully

       >0	Application exited with failure

       The following files are used by this application:

       /usr/bin/glib-genmarshal        The command-line executable for the application.

       /usr/share/gtk-doc/html/glib    Location of developer documentation
