RE: [Linux-streams] RE: delay routines

[Gurol Akman]

thanks dave,

 

i don't currently use the wakeup routines anyways; i'd just included them for completeness. so it's no problem at all...

 

regards -- gurol

Gurol:

I put these in but deleted the portion of the patch for wake_up_sync and wake_up_interruptible_sync.  In 2.4 kernels these depend upon an internal kernel routine that is not exported.

Thanks,
Dave

dave,
 
per your suggestions, i modified the following files:
 
    + osif.h
    + osif.c
    + exports.c
 
to provide support for the following kernel routines:
 
    + sleep_on_timeout
    + interruptible_sleep_on_timeout
    + wait_event
    + wait_event_interruptible
    + wake_up_sync
    + wake_up_interruptible_sync
 
could you pls review these changes and consider incorporating them in a future release (if you deem appropriate).
 
thank you in advance. regards,

follow up on question # 2 below:

 

i'm wondering

why

That's easy.  Because the AT&T SVR4 STREAMS programming guide does not include any such functions.  LiS is a STREAMS environment augmented by some Linux kernel interfacing routines, not a kernel interface with a STREAMS component.

Why don't you just code an abstraction of  your own for delay(9) and put the kernel code in it for Linux?

Or send a patch for osif.[ch] for the lis_sleep... functions?  Or send a patch to implement the Solaris compatible delay(9) function?
