Dealing with stack backtraces.

add_channel b ic n reads exactly n character from the input channel ic and stores them at the end of buffer b.

String type based on Bigarray, for use in I/O and C-bindings

Utility functions for marshalling to and from bigstring

A representation of CIDR netmasks (e.g.

Clock used to mark the progress of a timer.

purely functional command line parsing

Consume.string t ~len reads len characters (all, by default) from t into a new string and advances the lower bound of the window accordingly.

timedwait cond mtx timeout waits on condition variable cond with mutex mtx until either the condition is signalled, or until timeout expires.

Warning! this library assumes we are in a POSIX compliant OS.

add_finalizer b f ensures that f runs after b becomes unreachable.

lock mtx locks mtx, possibly waiting for it to be released first by another thread.

System interface.

Lightweight threads.

File descriptor.

Crc functions

daemonize makes the executing process a daemon.

converts a string to a date, in formats: * m/d/y * y-m-d (* valid iso8601_extended *) * DD MMM YYYY * DDMMMYYYY * YYYYMMDD

Deprecated should be used only by Core_extended.Deprecated_command.

epoll() - a linux I/O multiplexer of the same family as select() or poll().

The termination status of a process.

Backtrace.Exn has functions for controlling and printing the backtrace of the most recently raised exception.

The Expert module contains functions that novice users should avoid, due to their complexity.

File descriptor.

Peek and Poke functions access a value at pos from the lower bound of the window and do not advance.

Structure of entries in the groups database.

I/O-vectors for scatter/gather-operations

Module for simple closed intervals over arbitrary types that are ordered correctly using polymorphic compare.

Module for simple closed intervals over arbitrary types that are ordered correctly using polymorphic compare.

A non-moving (in the gc sense) contiguous range of bytes, useful for I/O operations.

no_seek and seek are defined and used in a similar manner to read_only and read_write.

Intentionally empty.

Interface to Linux-specific system calls

Mutual exclusion between processes using flock and lockf.

create like Mutex.create, but creates an error-checking mutex.

A nano-mutex is a lightweight mutex that can be used only within a single OCaml runtime.

An implementation neutral NFS lock file scheme that relies on the atomicity of link over NFS (see NFS Illustrated, atomicity for more information).

add t s shifts the time of day t by the span s.

Structure of entries in the passwd database

piece-wise linear interpolation from float-like types to float

create enforces that key values are non-decreasing.

Timing wheel is implemented as a priority queue in which the keys are non-negative integers corresponding to the intervals of time.

Similar to UnixLabels.open_process, but the second argument specifies the environment passed to the command.

Utility functions for dealing with the environment.

Resource limits

Resource usage -- For details, "man getrusage"

Wait until some input/output operations become possible on some channels.

of_system_int and to_system_int return and take respectively a signal number corresponding to those in the system's /usr/include/bits/signum.h (or equivalent).

Basic operations on spans

composable command-line specifications

Thread-safe queue module, using locks.

A module for representing absolute points in time, independent of time zone.

Timed events

A specialized priority queue for a set of time-based alarms.

This interface is only here to remind us to add a unit test whenever the interface of Timing_wheel changes.

Unsafe has submodules that are like their corresponding module, except with no range checks.

A pair of unix username and primary unix group.

Implements universally unique identifiers based on version 3 of the UUID specification.

Time-zone handling.
