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.
