Message boxes in eCos

Hi all, cyg_mbox_peek (), is always returning the count 1 less than the actual number of messages in the message box. When the message box is empty, then count is returned as 0. Why this is so?...

Hi,

Thanks Sepp for your suggestion.

The program is giving correct results now, using cyg_mbox_tryget () instead of cyg_mbox_get (). But still I have one doubt. The reason that you had specified for cyg_mbox_get () is okay, but then using that concept cyg_mbox_peek () would always had returned the count as 0?

With regards,

Sanjay
