[lwip-users] request for help

[Ethashamuddin Mohammed]

Hello

 

I would like to write an application program, one as client and the other as server using TCP module of LWIP as shown below.

 

client -----> TCP lib(LWIP) ------> INET Raw socket -----user space---------|-------kernel space------------->  IP------>DLL

Server-----> TCP lib(LWIP) ------> INET Raw socket -----user space---------|-------kernel space------------->  IP------>DLL

 

I know the usage of INET Raw socket(SOCK_RAW), but i have no idea about the usage of TCP layer of LWIP library.

 

Please let me know a sample program which uses TCP layer(LWIP) in user space and communicate the data.

 

I would be really happy, if somebody could give me the info in this regard.

 

With regards,

Shamuddin.
