#include <netdb.h>
int endnetent_r(struct netent_data
*netent_data_struct_addr)
Service Program Name: QSOSRV2
Default Public Authority: *USE
Threadsafe: Yes
The endnetent_r() function is used to close the network database
file. The file is opened by those functions that retrieve information about a
network (for example, getnetent_r()).
Specifies the pointer to the netent_data structure, which is used to pass
and preserve results between function calls. The field net_control_blk in the
netent_data structure must be initialized with hexadecimal zeros before its
initial use. If compatibility with other platforms is required, then the entire
netent_data structure must be initialized with hexadecimal zeros before initial
use.
Authorities
No authorization is required.
Return Value
The endnetent_r() function returns an integer. Possible values
are:
-1 (unsuccessful call)
0 (successful call)
The struct netent_datadenoted by
netent_data_struct_addr is defined in
<netdb.h>.
Error Conditions
When the endnetent_r() function fails, errno can be set
to:
[EINVAL]
The netent_data structure was not properly
initialized to hexadecimal zeros before initial use. For corrective action, see
the description for structure netent_data.
Usage Notes
When the _XOPEN_SOURCE macro defined to the value 520 or greater, the network
file is always closed. When the _XOPEN_SOURCE macro is not so defined, the network file will
not be closed if a setnetent_r() call with a nonzero parameter value was previously
done.
System i® Navigator or the following CL commands can be
used to access the network database file:
WRKNETTBLE (Work with Network Table Entries)
ADDNETTBLE (Add Network Table Entry)
RMVNETTBLE (Remove Network Table Entry)
When you develop in C-based languages and an application is compiled with
the _XOPEN_SOURCE macro defined to the value 520 or greater, the endnetent_r()
API is mapped toqso_endnetent_r98().
