Dekker's Algorithm

Can anyone help me in implementing Dekker's Algorithm for Mutual Exclusion
or tell me some web link
please help me thanks

I know you have Google, too.
Use it.

I had search but not find code for Dekker's Algo

Odd, because on that search, the very first result lists enough pseudocode that I, not knowing anything about the algorithm, could easily implement it. In fact it's written pretty much in C as is.
