Function SCNetworkConnectionCreateWithServiceID

pub unsafe extern "C-unwind" fn SCNetworkConnectionCreateWithServiceID(
    allocator: Option<&CFAllocator>,
    service_id: &CFString,
    callout: SCNetworkConnectionCallBack,
    context: *mut SCNetworkConnectionContext,
) -> Option<CFRetained<SCNetworkConnection>>

Available on crate feature SCNetworkConnection only.

Creates a new connection reference to use for getting the status or for connecting or disconnecting the associated service.

Parameter allocator: The CFAllocator that should be used to allocate memory for the connection structure. This parameter may be NULL in which case the current default CFAllocator is used. If this reference is not a valid CFAllocator, the behavior is undefined.

Parameter serviceID: A string that defines the service identifier of the connection. Service identifiers uniquely identify services in the system configuration database.

Parameter callout: The function to be called when the status of the connection changes. If this parameter is NULL, the application will not receive notifications of status change and will need to poll for updates.

Parameter context: The SCNetworkConnectionContext associated with the callout.

Returns: Returns a reference to the new SCNetworkConnection.
