Hmm... actually, I just found that a solution should present itself in the 3.4 kernel, when it comes out. I can't post a URL with where I got this from (because apparently I need 5 posts for that), but here's a quote from the API changes page:

Quote:

The PR_SET_CHILD_SUBREAPER prctl() operation allows a "service manager" process to mark itself as a sort of 'sub-init', able to stay as the parent for all orphaned processes created by the started services. All SIGCHLD signals will be delivered to the service manager. There is a corresponding PR_GET_CHILD_SUBREAPER prctl() operation. Planned users of this feature include D-Bus and systemd.

waiting for multiple childs - C - waitpid

Hi gurus, I would like to fork more children and then write their return values: so far I tried: #include <stdio.h> #include <stdlib.h> #include <errno.h> #include <unistd.h> #include <sys/types.h> #include <sys/wait.h> int main(void) { pid_t pid; int rv=0, i; ...

Hi folks, I am writing a simple program to understand how fork() and waitpid works, but it doesn't seem that is working like I wanted. if(fork()==0){ //el hijo pid1=getpid(); printf("\nSoy el hijo %d",pid1); }else { //el padre if (fork()==0) { //el hijo pid2=getpid();...

rpc.statd

rpc.statd(8)						      System Manager's Manual						      rpc.statd(8)

NAME

       rpc.statd, statd - Network status monitor daemon

SYNOPSIS

       /usr/sbin/rpc.statd [-c]

OPTIONS

       Available only on TruCluster Server systems. This option starts the clusterwide network status daemon, which helps provide highly available
       NFS service. Do not use -c directly. Highly available NFS service is configured by default and typically does not require intervention.	If
       you do need to start the clusterwide network status daemon, use the CAA command, caa_start cluster_lockd.

	      For more information, see the TruCluster Server Administration manual.

DESCRIPTION

       The  rpc.statd daemon monitors the status of the client and server sites in response to a request made by the local rpc.lockd daemon.  When
       a site failure is detected, the rpc.statd daemon notifies the local rpc.lockd daemon, which then processes the recovery of the locked files
       or file regions.

RESTRICTIONS

       The crash of a site is only detected on its recovery.

FILES

       A directory created by the statd daemon.  Each file name in the directory is the host name of a client or server that the statd daemon will
       notify upon its recovery.  A backup directory created by the statd daemon.  A file created by the statd daemon to store its state number.
