Function

CFSocketEnableCallBacks(_:_:)

Enables the callback function of a CFSocket object for certain types of socket activity.

Declaration

func CFSocketEnableCallBacks(_ s: CFSocket!, _ callBackTypes: CFOptionFlags)

Parameters

s

The CFSocket object to modify.

callBackTypes

A bitwise-OR combination of CFSocket activity types that should cause the callback function of s to be called. See CFSocketCallBackType for a list of callback types.

Discussion

If a callback type is not automatically reenabled, you can use this function to enable the callback (once).

This call does not affect whether the callback type will be automatically reenabled in the future; use CFSocketSetSocketFlags(_:_:) if you want to set a callback type to be reenabled automatically.

Be sure to enable only callback types that your CFSocket object actually possesses and has requested when creating the CFSocket object; the result of enabling other callback types is undefined.
