RTOS/TM4C1294NCPDT: tcp_output() in TI NDK with RTOS

Part Number: TM4C1294NCPDT

Tool/software: TI-RTOS

Hi,

I am moving my application from using lwip tcp/ip stack to NDK with RTOS. I have a question for equivalent of tcp_output() function (forcing data transmission not putting to queue). I looked in NDK Reference Guide but didn't find equivalent.

Thank you in advance.

tcp_output is proprietary to lwIP. The NDK supports standard BSD socket calls, proprietary calls and zero-copy calls. The best would probably be to convert to standard BSD socket calls.

Hi Todd,

Thank you for your response. I am in the process of converting to BSD style. Just wanted to know if there is any equivalent of tcp_output().

Setting the TCP_NODELAY option via setsockopt() should be the equivalent of tcp_output().

Where setting the TCP_NODELAY option on a socket disables Nagle's algorithm.
