1998-07-24 Martin Baulig <martin@home-of-linux.org> * sysdeps/{kernel, linux}/*.c: Replaced `glibtop_init_r' with `glibtop_init_s'. * sysdeps/sun4/open.c (glibtop_init_p): Removed `program_name' parameter. * sysdeps/osf1/glibtop_suid.h: New file. * sysdeps/osf1/glibtop_server.h: Now correctly using `(1 << GLIBTOP_SYSDEPS_*)' instead of `GLIBTOP_SYSDEPS_*'. * sysdeps/osf1/open_suid.c (glibtop_init_p): New function. * sysdeps/osf1/proc*.c: Done some more work here.

* buf->flags is only set if the call succeeded, in this case pids_chain,
|
|
* a list of the pids of all currently running processes is returned,
|
|
* buf->number is the number of elements of this list and buf->size is
|
|
* the size of one single element (sizeof (unsigned)). The total size is
|
|
* stored in buf->total.
|
|
*
|
|
* The calling function has to free the memory to which a pointer is returned.

*
|

* On error, NULL is returned and buf->flags is zero. */
