Apple

Thanks for interest MIKE.

I am preparing an application where I can manage the MAC machines processes.

For example: quitting the process.

For this I have prepared one kinfo_proc structure and populated it.

Using kp_proc.p_comm and kp_proc.p_pid I am preparing a another structure CProcessEntry which has pid and process name

and store that structure in vector array.

Now when we pass particular name say firefox, it should be effective enough to quit firefox of only that user.

To get the user id I got reply from [mm w] as below:

struct _pcred e_pcred; /* process credentials */

struct _ucred e_ucred; /* current credentials */

struct kinfo_proc *kp;

struct eproc *ep;

ep = &kp->kp_eproc;

uid = ep->e_ucred.cr_uid;

I feel this will work. I will try this soon.

Another problem was we don’t have always the same name of application and process name.

Example, firefox.app application has process name firefox-bin. This will fail my application. I want to handle these cases.

Again I got few pointers from [mm w]. But I don’t have clear Idea of its implementation.

However I also discovered one more thing about java applications run under same process name JavaApplicationStub.

If I have two or more Java Application there process name is same i.e. JavaApplicationStub But There PSN are different.

How can I handle these special cases?

Thanks

Rahul

Rahul,

You seem confused. What are you trying to do?

Without explaining your overall objective, it will be difficult for us to give you relevant advice.

Hello Again,

I just noticed few things between process names and there app names.

For example, firefox.app process name is i.e. kp_proc.p_comm is firefox-bin.

I am just confused. If this is the case then my application may fail for several cases.

How can I handle these cases?

Thanks

Subject: kinfo_proc structure

Hello All,

I have a kinfo_proc populated. I am facing 2 problems mainly.

1. This one may be simple to answer but it is giving me tough time.

I want to find the user id with the associated process id. Process id is already available to us from kinfo_proc.

2. Another one is little wired. Once kinfo_proc is populated, one can think that it has been populated by all running process in the system.

Whereas it misses one ccollabgui.app process. And I can see its entry from ps-ef. Am I missing something?

Any help is highly appreciated.

Thanks

Rahul
