recvfrom_nw

The recvfrom_nw function receives data on an unconnected IPX socket created for

nowait operations.

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 for the socket, as returned by the call to socket_nw.

buffer_ptr

Character pointer to the data returned by the call to recvfrom_nw.

buffer_length

Integer length of the data buffer pointed to by buffer_ptr.
