netconn_write[]
err_t netconn_write ( struct netconn * aNetConn, const void * aData,
size_t aSize, u8_t aApiFlags );
- aNetConn : the netconn object the data is written to
- aData : address of beginning of the data to write
- aSize : the length of the data in bytes
- aApiFlags : either of
- NETCONN_NOCOPY if the data is stable for the time of the transmission (static data or heap)
- NETCONN_COPY if the data is not stable for the time of the transmission (stack)
Write data to an active netconn connection. See example in netconn_connect (). You might want to have a look to the Nagle Algorithm in the Raw API, Miscellaneous. Nagle handles the problem of small data to overhead ratios.
