/*
 ** NAME
 **   get_position - gets the position of the host or directory
 **                  in the FSA or FRA
 **
 ** SYNOPSIS
 **   int get_dir_position(struct fileretrieve_status *fra,
 **                        char                       *dir_alias,
 **                        int                        no_of_dirs)
 **   int get_host_position(struct filetransfer_status *fsa,
 **                         char                       *host_alias,
 **                         int                        no_of_hosts)
 **
 ** DESCRIPTION
 **   This function get_host_position() gets the position of host
 **   'host_alias' in the FSA (File Transfer Status Area) 'fsa'.
 **   The FSA consists of 'no_of_hosts' structures, i.e. for each
 **   host a structure of filetransfer_status exists.
 **
 **   Function get_dir_position() is very similar to the above
 **   function, only that it gets the 'dir_alias' from the FRA
 **   (File Retrieve Area).
 **
 ** RETURN VALUES
 **   Returns the position of the host 'host' in the FSA pointed
 **   to by 'fsa'. If the host is not found in the FSA, INCORRECT
 **   is returned instead.
