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);

  [Digital]  The following function is supported in order to maintain
  backward compatibility with previous versions of the operating system.

  void endprotoent_r(
	  struct protoent_data *proto_data);

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

  endprotoent():  XPG4-UNIX

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

PARAMETERS
  proto_data
	    [Digital]  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 second setprotent() call
  must be issued with a parameter equal to 0 (zero) in order to ensure that a
  following endprotoent() function will succeed.




NOTES
  [Digital]  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
  /etc/protocols
	    Contains protocol names.

  /etc/svc.conf
	    The database service selection configuration file.
