[lwip-devel] [patch #5211] Sockets: Non-blocking write support

[anonymous]

Follow-up Comment #2, patch #5211 (project lwip):

As this is a useful feature and is a step towards full BSD sockets
compliance, how about providing a second API such as:

netconn_write_extended (..oldparams.., u8_t block_flag)
{

}

The netconn_write() API can then remain as a simple wrapper function:

netconn_write (..oldparams..)
{
  return (netconn_write_extended (..., TRUE));
}

The sockets layer can take advantage of the new API, while still retaining
backwards compatibility.

I used this method recently to implement non-blocking connect() calls.
