about spawn flag

[Sinan Nalkaya]

hi, i am using os.spawn function, it works well but i need a flag that
allows function return the process id with exit/error code, is there
any or how can i do it, i can replace spawn with fork/exec if
necessary.
thanks.

os.P_WAIT waits until the spawned process finishes and returns its
exit/error code from the os.spawn call.

thank you but also i need a pid.also react like an os.P_NOWAIT.
if i summarize,
child proccess immediately returns the pid, if child exits also
returns the exit/error code
