Hey all,
we just ported from 1.3.2 to 1.4.1 and some of our programs stopped
working because the error codes the socket API returns apparently changed.
can someone explain, why ERR_ISCONN is mapped to EALREADY in line 145 of
sockets.c?
static const int err_to_errno_table[] = {
0, /* ERR_OK 0 No error, everything OK. */
ENOMEM, /* ERR_MEM -1 Out of memory error. */
ENOBUFS, /* ERR_BUF -2 Buffer error. */
EWOULDBLOCK, /* ERR_TIMEOUT -3 Timeout */
EHOSTUNREACH, /* ERR_RTE -4 Routing problem. */
EINPROGRESS, /* ERR_INPROGRESS -5 Operation in progress */
EINVAL, /* ERR_VAL -6 Illegal value. */
EWOULDBLOCK, /* ERR_WOULDBLOCK -7 Operation would block. */
EADDRINUSE, /* ERR_USE -8 Address in use. */
ERR_ISCONN, /* ERR_ISCONN -9 Already connected. */
<=== this would be how I'd like it ;o)
ECONNABORTED, /* ERR_ABRT -10 Connection aborted. */
ECONNRESET, /* ERR_RST -11 Connection reset. */
ENOTCONN, /* ERR_CLSD -12 Connection closed. */
ENOTCONN, /* ERR_CONN -13 Not connected. */
EIO, /* ERR_ARG -14 Illegal argument. */
-1, /* ERR_IF -15 Low-level netif error */
};
The interesting part is that EALREADY is not defined in the err.h of LwIP.
(In ours it is...)
kind regards,
