(First, you're talking libcurl stuff so the curl-library list would be a more
appropriate list than this and would reach the proper "crowd". I'm CC'ing my
response over there now.)

libcurl tells you the size of the data chunk and hands it to you. It always
treats data as a plain blob with potentially binary contents. The callback
example in getinmemory.c does as well and it has no problems with embedded
zero bytes in the data stream.

You just need to never try strlen() or any other function on the data that
assumes a trailing zero byte to signal the end of it.
