protocol_copyPropertyList(_:_:)

Declaration

func protocol_copyPropertyList(_ proto: Protocol, _ outCount: UnsafeMutablePointer<UInt32>?) -> UnsafeMutablePointer<objc_property_t>?

Parameters

• proto:

  A protocol.

• outCount:

  Upon return, contains the number of elements in the returned array.

Return Value

A C array of pointers of type objc_property_t describing the properties declared by proto. Any properties declared by other protocols adopted by this protocol are not included. The array contains *outCount pointers followed by a NULL terminator. You must free the array with free().

Discussion

If the protocol declares no properties, NULL is returned and *outCount is 0.
