PRIV_RESPAWN_AS(3) Subroutines PRIV_RESPAWN_AS(3)NAMEpriv_respawn_as - spawn a new instance of the process as the specified
user, possibly in a chroot jail.
SYNOPSIS
#include <privman.h>
int priv_respawn_as(void (*fnptr)(char * const *), char * const arg[],
const char *user, const char *chroot);
DESCRIPTION
This method, priv_respawn_as causes the application to run again, fall‐
ing out of priv_init with the original state intact. The current
process will continue unaffected. The function pointed to by fnptr
will be called with NULL-terminated the string array argument provided
in arg before the application returns from priv_init, allowing you to
change global state as required. The application will be running as
user in the chroot jail chroot. You can pass NULL for the user and the
chroot argmuments, in which case no chroot jail will be used, and the
user will be the default unprivileged user.
Unlike priv_rerunas(3) both slave processes will be able to use a Priv‐
man server. See priv_rerunas(3) for more details and examples.
priv_respawn_as requires that allow_rerun be set to true in the appli‐
cation's configuration file. If the application needs to use either
the user or chroot options, then runas_user and chroot will also have
to be set properly in the application's configuration file. See priv‐
man_conf(3) for more detail.

more details.
BUGS
This is not the simpliest primitive to understand. It might be nice if
program execution could continue from the point of invocation rather
than having to restart at priv_init().
It might be useful to be able to pass file descriptors.
