Re: YAJL Parser... getting a pointer to the data and length of the data?

Scott,

I think I see what you're saying.

I'm returning the length of the data, not the length of the actual buffer.

Here's what I mean..

{"name" : "Brad"}

This would return 4, correct? What would the buffer size be in this case?

For my needs I want the length of the data and the pointer to that said
data (and it seems to be working great for all lengths of data).

So how would a buffer length differ from the data or string length? Is it
the term "buffer" that is actually incorrect in this case then?

Thanks for looking into it!

Hi Brad,

So it looks like you changed yajl_get_string_buf() to calculate the buffer
size based on looking for a zero-terminator in 'buf'. This is not,
normally, now C strings work, though... Normally the x'00' terminator is
the end of the string, but the buffer size may be larger. For example, I
could declare a string as char data[256], and put just "hello" in the
string. The x'00' would be found after 5 characters, buf the buffer is
still 256 characters long. That is why my approach passed the buffer size
as a parameter.

I'm thinking the best approach is to create a hybrid of your solution and
mine... basically, use my solution, but return a length instead of just
on/off.

Thoughts?

Just for the record I did end up adding a couple subprocedures to YAJL. I
only ended up using the yajl_get_string_buf (with some slight
modifications
from your suggestion) though, not the UTF8 one. Although the
yajl_get_string_utf8 does seem to work as well.

Here they are if you want to add them to your distro:

I put the changes in an article so the formatting would be better. If you
want me to email you the changed source files just let me know and I'd be
happy to do so.
