[prog] C programming - capturing information sent to stdout

[Sue Stones]

I am trying to work out how to capture data sent to stdout for use 
elsewhere in the program.

Using libcurl I query a webpage, HTML code is returned and sent to 
stdout.  But I need to somehow capture this output and processes it to 
retrieve the data that I need.  What is the best way to do this?  So far 
I haven't found anything that works, but its some years since I did any 
C programming and I am a little rusty.  Any help would be most useful.
