glib-genmarshal - C code marshaller generation utility for GLib closures
glib-genmarshal
glib-genmarshal takes a list of marshallers to generate as input. The marshaller list is either read from standard input or from files passed as additional arguments on the command line.
The marshaller lists are processed line by line, a line can contain a comment in the form of
# this is a comment
or a marshaller specification of the form
RTYPE:PTYPE RTYPE:PTYPE,PTYPE RTYPE:PTYPE,PTYPE,PTYPE
(up to 16 PTYPEs may be present).
The RTYPE part specifies the callback's return type and the PTYPEs right to the colon specify the callback's parameter list, except for the first and the last arguments which are always pointers.
Currently, the following types are supported:
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 has to look like this:
VOID:VOID VOID:INT FLOAT:BOOLEAN,UCHAR
The generated marshallers have the arguments encoded in their function name. For this particular list, they are
g_cclosure_marshal_VOID__VOID(), g_cclosure_marshal_VOID__INT(), g_cclosure_marshal_FLOAT__BOOLEAN_UCHAR().
They can be used directly for GClosures or 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);
