sethostent

Opens and rewinds the network host database file.

#include  <netdb.h>

void sethostent  (int stay_open);

stay_open

Specifies a value used to indicate when to close the host database file:

0 (zero) to close the host database file after each call to the gethostbyname or gethostbyaddr routine.
nonzero to keep the host database file open after each call.

The sethostent routine opens or rewinds the network host database file and resets the file marker to the beginning of the file.

Passing a nonzero value to the stay_open parameter keeps the connection open until the endhostent or exit routine is called.
