Functions
g_cclosure_marshal_BOOLEAN__BOXED_BOXED
A GClosureMarshal function for use with signals with handlers that
take two boxed pointers as arguments and return a boolean. If you
have such a signal, you will probably also need to use an
accumulator, such as g_signal_accumulator_true_handled().
g_cclosure_marshal_BOOLEAN__BOXED_BOXEDv
The GVaClosureMarshal equivalent to g_cclosure_marshal_BOOLEAN__BOXED_BOXED().
g_cclosure_marshal_BOOLEAN__FLAGS
A GClosureMarshal function for use with signals with handlers that
take a flags type as an argument and return a boolean. If you have
such a signal, you will probably also need to use an accumulator,
such as g_signal_accumulator_true_handled().
g_cclosure_marshal_BOOLEAN__FLAGSv
The GVaClosureMarshal equivalent to g_cclosure_marshal_BOOLEAN__FLAGS().
g_cclosure_marshal_STRING__OBJECT_POINTER
A GClosureMarshal function for use with signals with handlers that
take a GObject and a pointer and produce a string. It is highly
unlikely that your signal handler fits this description.
g_cclosure_marshal_STRING__OBJECT_POINTERv
The GVaClosureMarshal equivalent to g_cclosure_marshal_STRING__OBJECT_POINTER().
g_cclosure_marshal_VOID__BOOLEAN
A GClosureMarshal function for use with signals with a single
boolean argument.
g_cclosure_marshal_VOID__BOOLEANv
The GVaClosureMarshal equivalent to g_cclosure_marshal_VOID__BOOLEAN().
g_cclosure_marshal_VOID__BOXED
A GClosureMarshal function for use with signals with a single
argument which is any boxed pointer type.
g_cclosure_marshal_VOID__BOXEDv
The GVaClosureMarshal equivalent to g_cclosure_marshal_VOID__BOXED().
g_cclosure_marshal_VOID__CHAR
A GClosureMarshal function for use with signals with a single
character argument.

A GClosureMarshal function for use with signals with one
double-precision floating point argument.
g_cclosure_marshal_VOID__DOUBLEv
The GVaClosureMarshal equivalent to g_cclosure_marshal_VOID__DOUBLE().
g_cclosure_marshal_VOID__ENUM
A GClosureMarshal function for use with signals with a single
argument with an enumerated type.
g_cclosure_marshal_VOID__FLAGS
A GClosureMarshal function for use with signals with a single
argument with a flags types.
g_cclosure_marshal_VOID__FLAGSv
The GVaClosureMarshal equivalent to g_cclosure_marshal_VOID__FLAGS().
g_cclosure_marshal_VOID__FLOAT
A GClosureMarshal function for use with signals with one
single-precision floating point argument.
g_cclosure_marshal_VOID__FLOATv
The GVaClosureMarshal equivalent to g_cclosure_marshal_VOID__FLOAT().
g_cclosure_marshal_VOID__INT
A GClosureMarshal function for use with signals with a single
integer argument.
g_cclosure_marshal_VOID__LONG
A GClosureMarshal function for use with signals with with a single
long integer argument.
g_cclosure_marshal_VOID__OBJECT
A GClosureMarshal function for use with signals with a single
GObject argument.
g_cclosure_marshal_VOID__OBJECTv
The GVaClosureMarshal equivalent to g_cclosure_marshal_VOID__OBJECT().
g_cclosure_marshal_VOID__PARAM
A GClosureMarshal function for use with signals with a single
argument of type GParamSpec.
g_cclosure_marshal_VOID__PARAMv
The GVaClosureMarshal equivalent to g_cclosure_marshal_VOID__PARAM().
g_cclosure_marshal_VOID__POINTER
A GClosureMarshal function for use with signals with a single raw
pointer argument type.
g_cclosure_marshal_VOID__POINTERv
The GVaClosureMarshal equivalent to g_cclosure_marshal_VOID__POINTER().
g_cclosure_marshal_VOID__STRING
A GClosureMarshal function for use with signals with a single string argument.
g_cclosure_marshal_VOID__STRINGv
The GVaClosureMarshal equivalent to g_cclosure_marshal_VOID__STRING().
g_cclosure_marshal_VOID__UCHAR
A GClosureMarshal function for use with signals with a single
unsigned character argument.
g_cclosure_marshal_VOID__UCHARv
The GVaClosureMarshal equivalent to g_cclosure_marshal_VOID__UCHAR().
g_cclosure_marshal_VOID__UINT
A GClosureMarshal function for use with signals with with a single
unsigned integer argument.
g_cclosure_marshal_VOID__UINT_POINTER
A GClosureMarshal function for use with signals with an unsigned int
and a pointer as arguments.
g_cclosure_marshal_VOID__UINT_POINTERv
The GVaClosureMarshal equivalent to g_cclosure_marshal_VOID__UINT_POINTER().
g_cclosure_marshal_VOID__ULONG
A GClosureMarshal function for use with signals with a single
unsigned long integer argument.
g_cclosure_marshal_VOID__ULONGv
The GVaClosureMarshal equivalent to g_cclosure_marshal_VOID__ULONG().
g_cclosure_marshal_VOID__VARIANT
A GClosureMarshal function for use with signals with a single
GVariant argument.
g_cclosure_marshal_VOID__VARIANTv
The GVaClosureMarshal equivalent to g_cclosure_marshal_VOID__VARIANT().
g_cclosure_marshal_generic_va
A generic GVaClosureMarshal function implemented via
libffi.
since: 2.30
g_cclosure_new
Creates a new closure which invokes callback_func with user_data as
the last parameter.
g_cclosure_new_object
A variant of g_cclosure_new() which uses object as user_data and
calls g_object_watch_closure() on object and the created
closure. This function is useful when you have a callback closely
associated with a GObject, and want the callback to no longer run
after the object is is freed.
g_cclosure_new_object_swap
A variant of g_cclosure_new_swap() which uses object as user_data
and calls g_object_watch_closure() on object and the created
closure. This function is useful when you have a callback closely
associated with a GObject, and want the callback to no longer run
after the object is is freed.
g_cclosure_new_swap
Creates a new closure which invokes callback_func with user_data as
the first parameter.
