Re: Spawn API - Setting Flags

[Scott Klement <rpg400-l@xxxxxxxxxxxxxxxx>]

Flags are a subfield of the inheritance data structure.  You can set 
more than one flag by adding them together.

inh = *ALLx'00';
int.flags = SPAWN_SETLOGJOBMSGNONE_NP
          + SPAWN_SETJOBNAMEPARENT_NO;

pid = spawn(path: 0: *omit: inh: argv: envp);

In this example, I've specified two flags.  One to tell it not to log 
messages, and another to tell it to use the job name of the parent job.

Since there won't be a job log, it'd be wise to use waitpid() -- which I 
prefer to use in conjunction with SIGCHLD -- to monitor the status of 
the job you spawned.
