KwikNet TCP/IP Sockets

Returns ...continued

The error indicator for socket

s is set to define the reason for failure. Use

kn_errno() to retrieve the error code.

EBADF The socket descriptor s is invalid.

EINVAL Parameter iovecp or iovcnt is invalid or

the buffer length in a data vector was declared to be

less than 0 or the sum of the data vector lengths

exceeds the maximum size of an integer.

ENOTCONN The socket is not connected.

EWOULDBLOCK The socket is marked non-blocking and no data is

available for reading.

ESHUTDOWN The peer has closed the connection and no data is

available for reading.

ENOBUFS Memory needed to service the request is unavailable.

Restriction If there is no data available at the socket, the caller will be blocked waiting

for data to arrive unless the socket s is marked as non-blocking. In the

latter case, the caller will resume with a -1 error status and the error code

EWOULDBLOCK will be stored in the socket descriptor.

Restriction On 16-bit processors, the amount of data which can be received is

restricted to 32767 bytes because the value returned by kn_readv() is a

signed integer.

See Also kn_connect(), kn_recv(), kn_recvfrom(),

kn_socket(), kn_writev()
