sorry guys, i'm a bit confuse about c++ and c

i'm reading your fastbit udf code

at /fb_udf.h
you have a C code, right?
and at fb_udf.cpp a c++ code

you can mix c and c++ at the same code?


at udf.h
what this do?

"
extern "C" {
"
those functions should be undestood as "C" instead of "C++", or compiler should "export" those c++ function to "C" "code", or something related to C and namespaces ?

sorry it's not mysql specific but i'm not finding some C++ plugins examples

:D nice
what i will is something like:

1) a plugin daemon that receive a tcp/ip connection with a double linked list "feed" (something like:  clear list, delete from position x to y, delete position x, insert at position x, update position x, move position x to y)
2) save this feed to a myisam/spider/innodb/anyother engine (i'm thinking about using a mysql handler api) (i didn't check how it works, but i think handler sock use it)
3) keep the double linked list at memory (reconstruct the list when server shutdown, maybe make some snapshots to avoid a long reconstruct, something like after X lines of feed, save the list, or after x minutes)
4) a engine to read the double linked list at memory (i don't know yet how do this, but i will need some control about reading a shared memory, how to access this shared memory from daemon plugin using storage engine)
5) a engine to read information about what daemon is doing (like 4)
6) at same plugin daemon, create a tcp/ip connection to "export" the same feed to others users (just a proxy, not a big problem)

at top level i think i will have 1 daemon plugin + 1 storage engine plugin

i'm thinking about c++ 11 cause it have double linked lists, threads, atomic, sockets, and i dont need others libs (maybe i'm wrong, but that was my first impression about c++11)

Hi,

My fastbit UDF use C++ 11 no problem.

Sure, you  can use any language you want, C++11 is perfectly fine too.
cmake doesn't care.
