Description

When using the endhostent subroutine in DNS/BIND name service resolution, endhostent closes the TCP connection which the sethostent subroutine set up.

When using the endhostent subroutine in NIS name resolution or to search the /etc/hosts file, endhostent closes the /etc/hosts file.

Note

If a previous sethostent subroutine is performed and the StayOpen parameter does not equal 0, the endhostent subroutine closes the /etc/hosts file. Run a second sethostent subroutine with the StayOpen value equal to 0 in order for a following endhostent subroutine to succeed. Otherwise, the /etc/hosts file closes on an exit subroutine call .

Files

/etc/hosts	Contains the host name database.
/etc/netsvc.conf	Contains the name service ordering.
/usr/include/netdb.h	Contains the network database structure.
