Description:
for the system I use -- SSH secure Shell Client .

in order to do job control ush must keep track of its children.use a list object similar to the one used in program 2.4 to keep a program history.the nodes in the list should have the following structure:

typedef enum jstatus
{ FOREGROUND,BACKGROUND,STOPPED,DONE,TERMINATED}
job_status_t;

typedef struct job_struct {
char *cmdstring;
pid_t pgid;
int job;
job_status_t jobstat;
struct job_struct *next_job;
}joblist_t;

static joblist_t *job_head = NULL;
static joblist_t *job_tail = NULL;

place the list structure in a seprate file along with the following function to manibulate the job list:

1- the add_list function adds the specified job to alist.the prototype for add_list is
int add_list(pid_t pgid, char *cmd, job_status_t status);
the pgid is the process group ID,and cmd is the command string for the job.the status value can be either FOREGROUND or BACKGROUND .the add_list function returns the job number if successful or -1 on failure.
2- the delete_ list function removes the node corresponding to the specified job from a list.The prototype for delete_list is
int delete_list(int job);
the delete_list returns the job number if the node is successfully deleted or -1 on failure.be sure
to free all space associated with the deleted node.
3-the show _jobs function outputs a list of jobs and each one's status .use a format similar to
[job] status pgid cmd

4-the set_status function sets the status value of the node of the corresponding job to either
FOREGROUND or BACKGROUND .its prototype is
int set_status(int job,job_status_t status);
the set_status function return 0 to success and -1 to failure.

(Excellent)
   
Am I right in assuming this project to be limited to list manipulation functions and driver program and independent of ush?

Regards
