GdkPixbufSaveFunc

Specifies the type of the function passed to gdk_pixbuf_save_to_callback(). It is called once for each block of bytes that is "written" by gdk_pixbuf_save_to_callback(). If successful it should return %TRUE. If an error occurs it should set @error and return %FALSE, in which case gdk_pixbuf_save_to_callback() will fail with the same error.

alias GdkPixbufSaveFunc = int function(char* buf, size_t count, GError** error, void* data)
