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

[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

Contains protocol names. The database service selection configuration file.
