1.2.3.1.37 TCPIP_TCP_Peek Function
C
uint8_t TCPIP_TCP_Peek(
TCP_SOCKET hTCP,
uint16_t wStart
);
Description
This function peaks at one byte in the TCP RX buffer/FIFO without removing it from the buffer.
Preconditions
TCP is initialized.
Parameters
| Parameters | Description |
|---|---|
| hTCP | The socket to peek from (read without removing from stream). |
| wStart | Zero-indexed starting position within the FIFO to peek from. |
Remarks
Note that this function is inefficient and its use is discouraged. A buffered approach (TCPIP_TCP_ArrayPeek) is preferred.
