3 * Bacula Director -- fd_cmds.c -- send commands to File daemon
5 * Kern Sibbald, October MM
7 * This routine is run as a separate thread. There may be more
8 * work to be done to make it totally reentrant!!!!
10 * Utility functions for sending info to File Daemon.
11 * These functions are used by both backup and verify.
