/* Fetch list of currently running processes.
* The interface of this function is a little bit different from the others:
* 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.
*
* IMPORTANT NOTE:
* On error, this function MUST return NULL and set buf->flags to zero !
* On success, it returnes a pointer to a list of buf->number elements
* each buf->size big. 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. */
