accept_nw

The accept_nw function checks for connections on an existing nowait socket. It is

designed to be followed first by a call to socket_nw to create a new socket, then a

call to accept_nw2 to accept the connection on the new socket.

error

is the return value. If the call is successful, a zero is returned. If the call is not

successful, -1 is returned. If the call failed, the external variable errno is set as

indicated below in “Errors.”

socket

specifies the socket number, created by a previous socket_nw call, to be used to

check for connections.

from_ptr

points, on return, to the remote IPX address data structure for the new connection

from which the connection was initiated. This is an output parameter.

from_len1

points to a value indicating the size in bytes of the structure pointed to by

from_ptr. Set the from_len1 used in the accept_nw call to point to the size of

the sockaddr struct before making the call. accept_nw will then return the
