send_nw2

The send_nw2 function sends data on a connected socket. Unlike the send and

send_nw calls, the send_nw2 call does not store the number of bytes sent in the data

buffer. Therefore, the send_nw2 call does not require the application to allocate

2 bytes in front of its data buffer to receive the number of bytes sent. Instead, the

application should call socket_get_len to obtain the number of bytes sent.

nsent

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.

nbuffer_ptr

specifies the data to be sent. Call AWAITIOX to complete the send_nw2 call.

nbuffer_length

is the size of the buffer pointed to by nbuffer_ptr.
