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.
