Subject: [vpp-dev] why define an unused var
hi there,
i'm reading vpp code, and confused with this code: int rv __attribute__
((unused)) = write (2, "Main heap allocation failure!\r\n", 31); why it define
a var named rv, but never used, what d
big deal really if
it’s done the way you show. It’s likely this came about incrementally in the
code.
Chris.
