TCPIP_TCP_Peek Function

C

uint8_t TCPIP_TCP_Peek(
    TCP_SOCKET hTCP, 
    uint16_t wStart
);

This function peaks at one byte in the TCP RX buffer/FIFO without removing it from the buffer.

TCP is initialized.


Parameters	Description
hTCP	The socket to peek from (read without removing from stream).
wStart	Zero-indexed starting position within the FIFO to peek from.

Note that this function is inefficient and its use is discouraged. A buffered approach (TCPIP_TCP_ArrayPeek) is preferred.
