endprotoent(3)						     Library Functions Manual						    endprotoent(3)

NAME

       endprotoent, endprotoent_r - Close the network protocols database file

LIBRARY

       Standard C Library (libc.so, libc.a)

SYNOPSIS

       #include <netdb.h>
       void endprotoent(void);

       [Tru64  UNIX]  The following function is supported in order to maintain backward compatibility with previous versions of the operating sys-
       tem.  void endprotoent_r(
	       struct protoent_data *proto_data);

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       endprotoent():  XNS4.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       [Tru64 UNIX]  For endprotoent_r() only, this is data for the protocol database.

DESCRIPTION

       The endprotoent() function closes either the local /etc/protocols file or the NIS distributed protocols file, previously  opened  with  the
       getprotoent(), getprotobyname(), or getprotobynumber() function. To determine which file or files to search, and in which order, the system
       uses the switches in the /etc/svc.conf file.

       If the most recent setprotent() function has been performed with a nonzero parameter, the endprotoent() function will not close the network
       protocols  database file.  In this instance, the network protocols database file is not closed until a call to the exit() function.  A sec-
       ond setprotent() call must be issued with a parameter equal to 0 (zero) in order to ensure that a  following  endprotoent()  function  will
       succeed.

NOTES

       [Tru64  UNIX]  The  endprotoent_r()  function is the reentrant version of the endprotoent() function.  It is supported in order to maintain
       backward compatibility with previous versions of the operating system.  The netdb.h header file defines the protoent_data structure.

ERRORS

       Current industry standards do not define error values for the endprotoent() function.

FILES

       Contains protocol names.  The database service selection configuration file.
