Memory management control and statistics; finalised values.

For many students of ocaml, using hashtables is complicated by the functors.

Values returned by hash must be non-negative.

mod and div operators that have the right behavior on negative numbers, that is, x % y always returns a value between 0 and y-1.

This module defines the Map module for Core.Std.

Formatting error and exit functions

Core_queue is a wrapper around OCaml's standard Queue module that follows Core idioms and adds some functions.

Pseudo-random number generators (PRNG).

if res = partition_tf set ~f then fst res are the elements on which f produced true, and snd res are the elements on which f produces false

no_raise is the identity, but by using 'a no_raise in a sexpable type, the resulting use sexp_of_no_raise protects the conversion of 'a to a sexp so that if it fails, one gets a sexp with an error message about the failure, rather than an exception being raised.

Core_stack is a replacement for OCaml's standard Stack module that follows Core idioms and adds some functions.

An extension of the standard StringLabels.

System interface.

Lightweight threads.

File descriptor.

Crc functions

daemonize ?(redirect_stdout=`Dev_null) ?(redirect_stderr=`Dev_null) ?(cd = "/") ?umask=[0] () makes the current executing process a daemon, and dups "/dev/null", redirect_stdout, redirect_stderr to stdin/stdout/stderr.

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

A double ended queue that can shrink and expand on both ends.

doubly-linked lists

Library for lazily constructing string error messages.

Operations for escaping and unescaping strings, with paramaterized escape and escapeworthy characters.

The termination status of a process.

Raised when finalization after an exception failed, too.

File descriptor.

Floating-point representation and utilities.

various combinators for functions

A "force_once" is a thunk that can only be forced once.

A simple polymorphic functional queue.

Structure of entries in the groups database.

A hash-heap is a combination of a heap and a hashtbl that supports constant time lookup, and log(n) time removal and replacement of elements in addition to the normal heap operations.

a hash-queue, where the values are of type 'a

The difference between Hashable and Hashable_t functors is that the former's result type doesn't contain type t and the latter does.

Min-heap implementation, adapted from CLR.

I/O-vectors for scatter/gather-operations

a signature for opaque identifier types.

In_channel collects all of the pervasive functions that work on in_channels.

Inherit comparability from a component.

Takes an int represented as a string ((-|+)?0-9+) and puts delimiter every 3 digits starting from the right.

An implementation of compressed integer sets using lists of integer ranges.

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.

Interface to Linux-specific system calls

Mutual exclusion between processes using flock and lockf.

Memoization code -- not re-entrant!

t >>= f returns a computation that sequences the computations represented by two monad elements.

of_string s accepts three-character abbreviations with any capitalization

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

create () returns a new, unlocked mutex.

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

Of_stringable and Of_sexpable each create an identifiable that uses string conversions for binable, sexpable, equality, hash, compare, and pp.

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

This module can be used to safely expose functions and values in signatures that can only be used in unit tests.

Option wraps the output x of successful functions in Some x.

Type for tracking errors in an Error.t.

normalize length_fun thing_with_length i is just i, unless i is negative, in which case it's length_fun thing_with_length + i.

Outputs a list of lines, each terminated by a newline character

Returns the fractional part and the whole (i.e.

Structure of entries in the passwd database

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

Interfaces used for hiding and replacing polymorphic compare.

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

Module for easily generating unit tests.

Resource limits

swap t1 t2 swaps the values in t1 and t2.

Resource usage -- For details, "man getrusage"

Result is often used to handle error messages.

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

This module implements an option ref that starts out as None, and may be set only once.

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).

The raison d'etre for Space_safe_tuple<N> is that OCaml doesn't properly free variables matched in tuple patterns.

Basic operations on spans

Thread-safe queue module, using locks.

A type for making staging explicit in the type of a function.

The functions from module State manipulate the current state of the random generator explicitely.

stable_dedup Same as dedup but maintains the order of the list and doesn't allow compare function to be specified (otherwise, the implementation in terms of Set.t would hide a heavyweight functor instantiation at each call).

create ?pos ?len base creates a substring of the base sequence of length len starting at position pos, i.e.

This module is here to avoid holding the runtime lock when doing an open_in_gen lock.

Our time module.

The difference between Hashable and Hashable_t functors is that the former's result type doesn't contain type t and the latter does.
