Hi Li,

You can use following code snippet to make socket as non_blocking

SlSockNonblocking_t enableOption;
enableOption.NonblockingEnabled = 1;
 // Enable/disable nonblocking mode
sl_SetSockOpt(SockID,SL_SOL_SOCKET,SL_SO_NONBLOCKING, (_u8 *)&enableOption,sizeof(enableOption));



Regards,
Jitendra

Hi,

If this sets the Socket to non-Blocking mode, how can I know when data is ready to be read on the socket?

To then call sl_Recv(), for example.

Thanks, Tom

Hey, guys!

Any updates on this? Is there any way to know if there is data available in the socket?

Appreciate your help!

Thanks and cheers,

Hi.

You should simply use the return value from the recv function

int iSize = sl_recv......

if it is positive, you've got iSize bytes awaiting in the buffer.

if it's EL_AGAIN - you've got to try again to read,

else - you've got an error.
