Re: [libmicrohttpd] How to get last error

[Christian Grothoff]

There are only really two reasons for MHD_create_post_processor to fail:
1) out of memory (highly unlikely)
2) the encoding is not specified in the headers
We do not explicitly set errno, so you cannot distinguish between
the two cases based on the return value; however, you could check
if the client has set a supported encoding before creating the PP.

If your Browser fails to supply the encoding but you know which one it
is, you can use MHD_set_connection_value to tell the PP which encoding
to expect, see also:

Happy hacking!
