bison & flex

[Sunil Kumar Jain]

 Hi;
 
I'm sunil kumar jain, and using "bison and flex" for msg parsing. Please let
me know whether c++ files can be generated using bison & flex or not.
After parsing the byte stream, I want to fill the decoded message in
a class object.Is is possible to parse the byte stream directly through the
buffer ( i.e. an array of character ) or first I'll have to put the array of
bytes in a file then parsing will be done? 
Please let me know earliest possible about this.
Waiting for your response.
 
thanx and regards
Sunil Kumar Jain
