Queues are described in Chris Okasaki's book, with a functional

The "mod" and the write barrier will significantly degrade performance vs C.
Probably faster to replace "mod" with if-based wrap around but there's
nothing you can do about the write barrier.

A small implementation of a FIFO queue implemented as a circular
buffer of fixed length:
type 'a circular_buffer = {
mutable pos : int;
mutable count : int;
data : 'a array;
size : int;
}
let create size dummy = {
pos = 0;
count = 0;
data = Array.make size dummy;
size;
}
let push

Hi List,
I want to implement sliding window algorithm (in place, no memory
copy), I wonder whether I need to write c code.
To make it clear and simple,
In c, you can record the head pointer of the array, and do the
modulo operations when get and set
In ocaml, it seems you hav
Just did another run to be sure. It does not do any swapping.

Just to make things very clear:
1) the ocaml compilers that the installer packages are built with
mingw-w64, so they don't depend on cygwin1.dll
2) the installer advertises cygwin as a convenience environment (so
that there's make, bash, and the like), but the executables produced by

I always heard that if you compile your program under the Cygwin
environment, then the application needs to be run under the Cygwin
environment as well; whereas if you use MinGW, you produce stand-alone
executables. Is that still the case?
It depends
Hi,
We have done some further investigation, and it does not seem to be memory
leakage. The application is a video streaming application, where we use
external processes to encode and decode the video. By configuring it in
different ways, we have found the problem to be in the code that is reading
