Method
GLibSourceset_callback_indirect
Declaration
void
g_source_set_callback_indirect (
GSource* source,
gpointer callback_data,
GSourceCallbackFuncs* callback_funcs
)
Description
Sets the callback function storing the data as a refcounted callback
“object”. This is used internally. Note that calling
g_source_set_callback_indirect() assumes
an initial reference count on callback_data, and thus
callback_funcs->unref will eventually be called once more
than callback_funcs->ref.
It is safe to call this function multiple times on a source which has already been attached to a context. The changes will take effect for the next time the source is dispatched after this call returns.
Parameters
callback_data-
Type:
gpointerPointer to callback data “object”.
The argument can be NULL.The data is owned by the caller of the method. callback_funcs-
Type:
GSourceCallbackFuncsFunctions for reference counting
callback_dataand getting the callback and data.The data is owned by the caller of the method.
