[uClibc]res_query() in uclibc and glibc?

[sam_chang at sercomm.com]

Hi all,
     When I wanted to use reslover to implement some DNS works, I got a problem.
I found the implementation of res_query seems to be different from glibc to
uclibc.
The answer length returns from res_query are not the same even I update the
latest uclibc version.
Last month, someone said that uclibc's res_query only returns the answer field
of the resource record portion
of the DNS response message. Would you tell me why uclibc works that way? I'll
appreciate a lot.
Thank you.
Sam
