endhostent Subroutine


Closes the /etc/hosts file.


Standard C Library (libc.a)


#include <netdb.h>
endhostent ()


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 (zero), then the endhostent subroutine closes the /etc/hosts file. Run a second sethostent subroutine with the StayOpen value equal to 0 (zero) in order for a following endhostent subroutine to succeed. Otherwise, the /etc/hosts file closes on an exit subroutine call .
