netwrite - send a message on a socket
int netwrite (int s, char *buf, int nbytes);
ssize_t netwrite_timeout (int s, void *buf, size_t nbytes, int timeout);
netwrite sends a message on a socket.
This routine returns the number of bytes if the operation was successful, 0 if the connection was closed by the remote end or -1 if the operation failed. In the latter case, serrno is set appropriately.
|EINTR||The function was interrupted by a signal.|
|EBADF||s is not a valid descriptor.|
|EAGAIN||The socket is non-blocking and there is no space available in the system buffers for the message.|
|EFAULT||buf is not a valid pointer.|
|EINVAL||nbytes is negative or zero.|
|ENOTSOCK||s is not a socket.|
|SECONNDROP||Connection closed by remote end.|
