clone equivalent on HP-UX?

[Srimalik]

Is there is any syscall available on HPUX which can be considered equivalent to clone in linux?

[James R. Ferguson]

Hi:

I suppose that 'vfork' is the closet counterpart to the Linux 'clone()':

vfork(hp) is more similar to vfork in linux.
I want somthing which takes args like CLOME_VM,CLONE_FS.

something which is used by pthread_create?

Hi (again):

You may be hard-pressed to find 1:1 equivalence since the LINUX kernel differs from the HP-UX (UNIX) one. You might get better answers if you describe exactly what it is you want to achieve. Is this a porting issue of a particular piece of code, for example, or is this a more abstract question?

This is not a porting issue, I was just looking for a function which creates a LWP/thread like entity in HPUX(I don't want to use pthread_create).

Not sure whether running a process using pthread_create under tusc will show me the call?

By definition tusc must show you the calls. But it is better if you use the pthread functions since libc won't work correctly unless libpthread is present.

[Srimalik]

tried tusc and gdb, it seems that _vp_create and _lwp_create are the functions which do that job but these two functions are not available to programers :-(.

>but these two functions are not available to programmers

(system calls) Didn't I say that. :-)
Why do you think you need to use these?

was just trying to find out whether we can skip pthread_create. This is just for educational purpose :D
