endprotoent(3)endprotoent(3)NAME
endprotoent, endprotoent_r - Close the network protocols database file
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 system.
void endprotoent_r(
struct protoent_data *proto_data );
LIBRARY
Standard C Library (libc)
STANDARDS
Interfaces documented on this reference page conform to industry stan‐
dards as follows:
endprotoent(): XNS4.0, XNS5.0
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 get‐
protoent(), getprotobyname(), or getprotobynumber() function. To deter‐
mine 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 net‐
work 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 suc‐
ceed.
NOTES
[Tru64 UNIX] The endprotoent_r() function is the reentrant version of
the endprotoent() function. It is supported in order to maintain back‐
ward 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 endpro‐
toent() function.
FILES
Contains protocol names. The database service selection configuration
file.
