netwrite - send a message on a socket
#include "net.h" 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. SETIMEDOUT Timed out.
