The Caml Hump: System :: System programming

Caml-Shcaml is an Ocaml library for Unix shell programming.

a small library written in O'Caml to get the current offset and flags of files opened by another process.

'Concurrent Cell' is a library for multi-thread programming with CML(Concurrent ML) style synchronous message passing communications. The Threads library, a part of OCaml, realizes the CML style event value, but does not support shared variables like ivar and mvar. This library implements these variables without creating any new thread. This means that ivar and mvar are lightweight and GC target.

An Environment Interaction module for Objective Caml. It's useful if you need to create a local copy of the current environment for modification.

"io" is an IO combinator library for safe I/O over strings and channels, in the style of "picklers" which can then be used with various backends to safely load and save data. Currently available backends include : human readable ASCII, binary and compressed binary. A type-independent command can convert between different representations. The representation for records and sum types is upwards compatible. Note that sharing and circular structures are not supported.

Lpd is a Line Printer Daemon (LPD) server library written entirely in OCaml. It allows to define your own actions for LPD events. An example of a spooler that prints jobs on win32 machines (through GSPRINT) is provided.

Thin bindings to various low-level system APIs which are not covered by Unix module.

OcamlFd is an extension library for the OCaml language, providing miscellaneous utility functions involving UNIX file descriptors.

The xapi toolstack, which provides the core Citrix Xenserver's functionalities, is a set of libraries and programs written in OCaml. It is approximately 200k lines of code developed from early 2006. Within Citrix, more than 40 people have already contributed to its source code.

An advanced scheduler. The basics of this scheduler is to implement a wrapper around Unix.select in order to be able to wait for events on a socket and/or a given delay and execute a task when one of the waited events occured.

These are a collection of monitoring and management tools for virtual machines.

OBus is a pure ocaml implementation of DBus. It aims to provide a clean and easy way for ocaml programmers to access and provide dbus services.

Sem is an OCaml module implementing support of POSIX semaphores. The package contains code in C and OCaml programming languages. Once compiled it makes a usual OCaml library usable in both byte-code and native code development.

Precise POSIX clock library for Ocaml. This library uses the clock_gettime(2) family of functions, to get precisions from below the milliseconds upto the nanoseconds depending on the platform (system and CPU). It lets you measure time from the real-time clock, monotonic clocks, or CPU-time clocks of the current process, of a remote process, or of a thread.

A small and not entirely usual CPU load monitor written in OCaml.

OCaml bindings for the Linux libaio library for asynchronous read/write operations.

Bindings to dbus. This is an alpha release (few memory leaks, missing some proper finalize function, and maybe segfault lurking), and the library is quite big so not everything is wrapped. However it should works for basic use, and the test program should be enough to get to know how to use it.

Ocaml bindings for the libevent API. The libevent API provides a mechanism to execute a callback function when a specific event occurs on a file descriptor or after a timeout has been reached. Furthermore, libevent also support callbacks due to signals or regular timeouts.

The library to make OCaml program act as a Windows service.
