		void *	ret,
		void **	args,
		void *	user_data )

GIFFIClosureCallback: @cif: the ffi_cif passed to [metho.nosp@m.d@GI.nosp@m.Repos.nosp@m.itor.nosp@m.y.Cal.nosp@m.labl.nosp@m.eInfo.nosp@m..cre.nosp@m.ate_c.nosp@m.losu.nosp@m.re] @ret: (out caller-allocates): a pointer to the memory used for the function’s return value @args: a vector of pointers to memory holding the arguments to the function @user_data: the user data passed to [metho.nosp@m.d@GI.nosp@m.Repos.nosp@m.itor.nosp@m.y.Cal.nosp@m.labl.nosp@m.eInfo.nosp@m..cre.nosp@m.ate_c.nosp@m.losu.nosp@m.re]

The function which will be called when a closure created with [metho.nosp@m.d@GI.nosp@m.Repos.nosp@m.itor.nosp@m.y.Cal.nosp@m.labl.nosp@m.eInfo.nosp@m..cre.nosp@m.ate_c.nosp@m.losu.nosp@m.re] is invoked.

The value of @ret is undefined if the function returns void.
