glib-genmarshal \- generates C code marshallers for GLib closures
.SH "SYNOPSIS"
.PP
\fBglib-genmarshal\fR [-\fB-body\fR] [-\fB-g-fatal-warnings\fR] [-\fB-header\fR] [-\fB-help\fR] [-\fB-internal\fR] [-\fB-nostdinc\fR | -\fB-stdinc\fR] [-\fB-prefix=\fIdir\fR\fR] [-\fB-skip-source\fR] [-\fB-version\fR] [\fB\fIfile\fR\fR\&...]
.SH "DESCRIPTION"
.PP
\fBglib-genmarshal\fR generates C code marshallers for callback functions
of the GClosure mechanism in the GObject sublibrary of GLib\&. The marshaller
functions have a standard signature\&. 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\&.
.PP
\fBglib-genmarshal\fR generates the specified list of marshallers\&.  The 
marshaller list is either read from standard input or from files passed as
additional arguments on the command line\&.
.SH "EXTENDED DESCRIPTION"
.PP
The marshaller lists are processed line by line\&. A line can contain a comment
in the following format:
.PP
.PP
.nf
# this is a comment
.fi
.PP
A marshaller list can contain a marshaller specification in the following
format:
.PP
.PP
.nf
\fIRTYPE\fR:\fIPTYPE\fR
\fIRTYPE\fR:\fIPTYPE\fR,\fIPTYPE\fR
\fIRTYPE\fR:\fIPTYPE\fR,\fIPTYPE\fR,\fIPTYPE\fR
# up to 16 \fIPTYPE\fRs may be present
.fi
.PP
RTYPE specifies the callback return type\&. PTYPE specifies the callback
parameter list, except for the first and the last arguments which are always
pointers\&.

\fBExample 1: Generating Marshallers\fR
.PP
This example shows how to generate marshallers for the following callback
functions:
.PP
.PP
.nf
void     foo (gpointer data1,
              gpointer data2);
void     bar (gpointer data1,
              gint param1,
              gpointer data2);
gfloat   baz (gpointer data1,
              gboolean param1,
              guchar param2,
              gpointer data2);
.fi
.PP
The marshaller list is as follows:
.PP
.nf
VOID:VOID
VOID:INT
FLOAT:BOOLEAN,UCHAR
.fi
.PP
The generated marshallers have the arguments encoded in their function name\&.
For this particular list, they are as follows:
.PP
.nf
g_cclosure_marshal_VOID__VOID()
g_cclosure_marshal_VOID__INT()
g_cclosure_marshal_FLOAT__BOOLEAN_UCHAR()
.fi
.PP
The generated marshallers can be used directly for GClosures or can be passed
in as the GSignalCMarshaller c_marshaller; argument upon creation of signals:
.PP
.nf
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);
.fi
.SH "EXIT STATUS"
