Hello,
I am using flex to scan a buffer I have in memory. I see the methods
yy_scan_string, yy_scan_bytes and yy_scan_buffer. These methods appear
to (1) copy data and (2) want to see two trailing NULLs at the end of
the buffer.
So my question is: is there a way to have flex use an existing in-memory
buffer that doesn't necessarily have two trailing NULLs without making
an entire copy of it? For example, can I just define the YY_INPUT macro
to read from my buffer or something similar?
As a follow up, what is the motivation for requiring the trailing NULLs?
If you know the length why does it matter that a buffer has these? I
could make my own yy_scan_bytes method but I am worried that flex will
not find the trailing NULLs it wants and everything will crash and burn.
Thanks!
Tim
