SYNOPSIS |
#include <netdb.h> void setprotoent(int stayopen);
DESCRIPTION |
setprotoent
opens the protocols file, that is, a file with the same
format as
/etc/protocols
in the UNIX environment. If the file is already open,
setprotoent
rewinds the file so that succeeding
getprotoent
calls can read it
sequentially. Specifying a nonzero value for
stayopen
causes the protocols file to remain open between subsequent
getprotobyname
and
getprotobynumber
calls. Refer to Network Administration for
information on naming the
protocols file for your system.
RETURN VALUE |
setprotoent
does not return a value.
PORTABILITY |
setprotoent
is portable to other environments, including most UNIX
systems, that implement BSD sockets.
IMPLEMENTATION |
This routine is ported directly from the BSD UNIX Socket Library.
