Hi:
I'm just reading the serial device driver of eCos.
In file /io/src/serial.c,the function cyg_selwakeup is used many times .
But I don't understand what's the meaning and usage of the function and I
can't find it in the document of the eCos .
someone help me
thanks !

It's actually mentioned in the "Guide to the eCos plug-in filesystem
architecture" at http://sources.redhat.com/ecos/docs-latest/
It's purpose is to wake up any threads waiting in select(), that are
waiting on fd's associated with serial drivers.
