Gawk [maynot] bug: Two-way IO getline stuff

[wxc]

Dear All,

http://www.gnu.org/software/gawk/manual/gawkinet/gawkinet.html

In this page, the manual bring a simple web server with GET-method handler.
My question is how can awk proccess a POST request?

since, in a http POST request header, content-lengh are supplied
clarifying the length of post-data, after the header, there are exactly
content-lengh bytes of post-data without any new line or something, that
means if getline try to read them, it get stuck waiting for the RS.

i think gawk may add some buffer control stuff, such as "getline var
NUMBER" means read exactly NUMBER bytes from input, "getline var NUMBER1
NUMBER2" means read NUMBER1 bytes with timeout NUMBER2 seconds.

Regards,
Wen
