[inline, virtual]

This function is called between fork and exec in the spawn() function.

It must not allocate memory unless you can guarantee that there is only one thread running -- on some platforms allocating memory between fork and exec when there were other threads running can result in a deadlock.

Any exception thrown of type PreExec::Error or derived from std::exception is reported in full back to the parent; any exception derived from PreExec::DontCatch is allowed to propagate out of Exec::spawn; and any other type of exception is reported as an unknown exception.

Parameters:

pparr

an array pointer that can be passed to the static functions close_pipes_on_exec() and setup_std_descriptors(). It includes pipes for each of the standard descriptors, plus any additional pipes used by Exec::spawn for communicating between child and parent before the execve occurs.

Implements BLOCXX_NAMESPACE::Exec::PreExec.
