public class TransPeekNamedPipe
extends SmbComTransaction

SMB1 transaction subcommand for peeking at data in a named pipe. This class implements the TRANS_PEEK_NAMED_PIPE transaction which allows reading data from a pipe without removing it, useful for checking if data is available before performing a blocking read.
