netread - receive a message from a socket
#include "net.h"
int netread (int s, char *buf, int nbytes);
ssize_t netread_timeout (int s, void *buf, size_t nbytes, int timeout);
netread receives a message from a socket. It overcomes the message fragmentation problem and always waits for all requested bytes to arrive or a timeout/error occurs.
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.
