Applies the masking transform to a payload in place, returning the transformed bytes.

API unit family: TMSFNCWebSocketCommon Declaring type: TTMSFNCWebSocketFrame

Syntax

FMX.TMSFNCWebSocketCommon.hppPascalC++

class function UnMask(var payload: TBytes; Key: Integer; Offset: Integer = 0): TBytes;

__classmethod System::Sysutils::TBytes __fastcall UnMask(System::Sysutils::TBytes &payload, int Key, int Offset = 0x0);

Key	Masking key applied byte by byte.
Offset	Index at which the transform starts; bytes before the offset are left unchanged. Defaults to 0.
