endprotoent, endprotoent_r - Close the network protocols
database file
#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 );
Standard C Library (libc)
Interfaces documented on this reference page conform to
industry standards as follows:
endprotoent(): XNS4.0, XNS5.0
Refer to the standards(5) reference page for more information
about industry standards and associated tags.
[Tru64 UNIX] For endprotoent_r() only, this is data for
the protocol database.
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.
[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.
Current industry standards do not define error values for
the endprotoent() function.
