2.3.35 FSCTL_PIPE_TRANSCEIVE Request
The FSCTL_PIPE_TRANSCEIVE request is used to send and receive data from an open pipe. Any bytes in the FSCTL input buffer are written as a binary large object (BLOB) to the input buffer of the pipe server.
The FSCTL input buffer does not have an associated structure. The buffer is a BLOB of bytes that are written into the associated pipe.
