Berkeley Sockets/iX Reference Manual

READ 

C Interface 

          int read (s, buf, len)
          int s;
          char *buf;
          int len;

Description 

The read function is similar to the recv call except there is no flags
parameter.  It behaves the same way as a recv call with flags set to
zero.

For more information about read or any other POSIX function, refer to the
MPE/iX Developer's Kit Reference Manual, Volume 1.

Return Value 

If the call is successful, it returns the number of bytes received.  If
the call fails, a -1 is returned, and an error code is stored in errno.
A zero is returned if the socket is blocking and the transport connection
to the remote node fails.
