When a process fork(), the child share the same file descriptors as his father. Thus, they share the same stdin. Quick and dirty exemple below (sorry for the ugly gets() call) :
#include <stdio.h>
#include <unistd.h>
int main()
{
char buf;
if (fork()) { /*parent */

kdb_init
kdb_init(8krb) kdb_init(8krb) Name kdb_init - initialize the Kerberos master database Syntax /var/dss/kerberos/bin/kdb_init [ realm-name ] [ database-name ] Arguments realm-name The realm of the Kerberos database. database-name A database specified so that the current and files are not overwritten. Description The utility creates and initializes the Kerberos master database. The utility creates the database files: and It also initializes the database by adding three database entries: the master database principal, a Kerberos default principal, the ticket-granting service princi- pal ( and the password changing principal, The master database principal is the entry to the database itself. You cannot use or modify the database without the master database pass- word. The Kerberos default principal provides a template for service principals. The ticket-granting service, is used by Kerberos principals to obtain tickets to communicate with other Kerberos principals. The password- changing principal is not used. If realm-name is omitted when you enter the command, prompts for it. The program also prompts for the master database key. You cannot manipulate the database without this key. By using database-name, you can create another database to prevent the current and files from being overwritten. After using to set up the master database, you may want to use the utility to hide the master database password on the database host machine. This enables Kerberos administration programs to access and manipulate the master database, without needing the password to be entered manually.
