TCPIP_TCP_ArrayPeek Function

C

uint16_t TCPIP_TCP_ArrayPeek(
    TCP_SOCKET hTCP, 
    uint8_t * vBuffer, 
    uint16_t wLen, 
    uint16_t wStart
);

Description

This function reads a specified number of data bytes from the TCP RX FIFO without removing them from the buffer. No TCP control actions are taken as a result of this function (ex: no window update is sent to the remote node).

Preconditions

TCP is initialized.

Parameters


Parameters	Description
hTCP	The socket to peek from (read without removing from stream).
vBuffer	Destination to write the peeked data bytes.
wLen	Length of bytes to peek from the RX FIFO and copy to vBuffer.
wStart	Zero-indexed starting position within the FIFO from which to start peeking.

Remarks

None.
