Re: Wait time for open

Right! The open() API has no way to set it to a wait period of time. The
main rule to open a stream file on the IFS while another job opened it
already, is that the first job getting privileges did not set exclusive,
non-shared open flags. Otherwise it should open the file successfully.

Hi,

AFAIK the open() API does return immediately with an error, if the file
could not be opened - like if it is already open in an non-shareable
open-mode.
