I have a "spawner" process that spawns other process within a vps. Problem is that the enivronment variables I pass with execve are not being passed to spawned processes. Does anyone know an easy way to do this?
Example code:
execve("/usr/sbin/vzctl", args, env);
where args={"exec", "101", "/path/to/process", ...}
Thanks!

unfortunately that would require me to modify every single process that we spawn...
Anyone else have any ideas?
Edit: I tried recreating vzctl calls so that I could just use execve as though I were in the vps but that also failed.
syscall(511, 101);
env_create.veid=101;
env_create.flags=VE_ENTER;
fd=open("/dev/vzctl", O_RDWR);
ioctl(fd, VZCTL_ENV_CREATE, &env_create);
close(fd);
The box ended up hardlocking...
