Hello all, I am trying to create n child processes and control them from a parent process; say make child 3 print its pid and then child 5 do the same and some other stuff. Is there a way to accomplishing this after all the child processes are created via a call to fork().
Thank you,

Hello.
I have a global function name func1() that I am sourcing in from script A. I call the function from script B. Is there a way to find out which script called func1() dynamically so that the func1() can report it in the event there are errors?
Thanks (2 Replies)
Hello,
How many child processes are actually created when running this code ?

I need a mechanism to fork child processes and all child processes should connect to a server.but the number of child processes should be limited(for ex:50)
Here's my pseudo, but I cant figure out how to limit the child process number. Should I use a semaphore? or what?

I'm likely going to explain this clumsily, so apologies in advance:
I have the following script:

I am trying to implement the below using Ksh script on a Lx machine.
There is a file(input_file) with 100K records. For each of these records, certain script(process_rec) needs to be called with the record as input. Sequential processing is time-consuming and parallel processing would eat up... (2 Replies)
is there a universal way of getting the children of a particular process? i'm looking for a solution that works across different OSes...linux, aix, sunos, hpux.
i did a search online and i kept finding answers that were specific to Linux..i.e. pstree.
i want to be able to specify a process... (2 Replies)

hv_vmbus
HYPER-V(4) BSD Kernel Interfaces Manual HYPER-V(4)NAME
hv_vmbus -- Hyper-V Virtual Machine Bus (VMBus) Driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in the system kernel configuration file:
device hyperv
DESCRIPTION
The hv_vmbus provides a high performance communication interface between guest and root partitions in Hyper-V. Hyper-V is a hypervisor-based
virtualization technology from Microsoft. Hyper-V supports isolation in terms of a partition. A partition is a logical unit of isolation,
supported by the hypervisor, in which operating systems execute.
The Microsoft hypervisor must have at least one parent, or root, partition, running Windows Server operating system. The virtualization
stack runs in the parent partition and has direct access to the hardware devices. The root partition then creates the child partitions which
host the guest operating systems.
Child partitions do not have direct access to other hardware resources and are presented a virtual view of the resources, as virtual devices
(VDevs). Requests to the virtual devices are redirected either via the VMBus or the hypervisor to the devices in the parent partition, which
handles the requests.
The VMBus is a logical inter-partition communication channel. The parent partition hosts Virtualization Service Providers (VSPs) which com-
municate over the VMBus to handle device access requests from child partitions. Child partitions host Virtualization Service Consumers
(VSCs) which redirect device requests to VSPs in the parent partition via the VMBus. The Hyper-V VMBus driver defines and implements the
interface that facilitate high performance bi-directional communication between the VSCs and VSPs. All VSCs utilize the VMBus driver.
SEE ALSO hv_ata_pci_disengage(4), hv_netvsc(4), hv_storvsc(4), hv_utils(4)HISTORY
Support for hv_vmbus first appeared in FreeBSD 10.0. The driver was developed through a joint effort between Citrix Incorporated, Microsoft
Corporation, and Network Appliance Incorporated.

FreeBSD support for hv_vmbus was first added by Microsoft BSD Integration Services Team <bsdic@microsoft.com>.
