Signal_info — Struct representing a signal.

type t

Signal_info represents a signal. It's a sub-struct of Callable_info and contains a set of flags and a class closure. See Callable_info for information on how to retreive arguments and other metadata from the signal.

val signalinfo : t Ctypes.structure Ctypes.typ
val true_stops_emit : t Ctypes.structure Ctypes.ptr -> bool

Obtain if the returning true in the signal handler will stop the emission of the signal.

Obtain the flags for this signal info. See GSignalFlags for more information about possible flag values.

Obtain the class closure for this signal if one is set. The class closure is a virtual function on the type that the signal belongs to. If the signal lacks a closure None will be returned. In order to avoid circular call graph between Signal_info and VFunc_info, this function will return a Callable_info. It is upto the user to use GIVSignalInfo.from_callableinfo in order to have the VFunc_info.

Just cast OCaml Ctypes signal info to base info

Add unref of the C underlying structure whith Gc.finalise.

Return a Signal_info.t from a Base_info.t, the underlying C structure ref count is increased and the value is Gc.finalis"ed" with Base_info.baseinfo_unref.

Return a Base_info.t from a Signal_info, the underlying C structure ref count is increased and the value is Gc.finalis"ed" with Base_info.baseinfo_unref.
