Guardian Native C Library Calls Reference Manual (G06.29+, H06.08+, J06.03+)

Guardian Native C Library Calls (a - e) _Exit(3)
• If the exit of a process causes a process group to become orphaned, and if any member of
the newly orphaned process group is stopped, then a SIGHUP signal followed by a
SIGCONT signal is sent to each member of the orphaned process group.
• Locks set by the fcntl( ) function are removed.
Use From the Guardian Environment
The _Exit() function can be called from any Guardian process as well as from OSS processes.
Guardian processes, however, have no OSS process ID (PID) and therefore have no wait con-
siderations.
NOTES
Open System Services currently does not support Common-Usage C.
RETURN VALUES
The _Exit() function does not return.
