[lwip-users] Socket API inconsistency

[Kjell-Erik Klevan]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Our web server sends a lot of data xml data. 

When the size is larger than the size of an unsigned short (u16_t), the
lwip_send fails to send all data due to an inconsistency in the socket API.

The lwip_send function API uses an 'int' size while the netwconn_write uses
an 'u16_t' size.

 

int

lwip_send(int s, void *data, int size, unsigned int flags)

 

err_t

netconn_write(struct netconn *conn, void *dataptr, u16_t size, u8_t copy)
