# TCMalloc

This repository contains the TCMalloc C++ code.

TCMalloc is Google's customized implementation of C's `malloc()` and C++'s

`operator new` used for memory allocation within our C and C++ code. TCMalloc is

a fast, multi-threaded malloc implementation.

## Building TCMalloc

[Bazel](https://bazel.build) is the official build system for TCMalloc.

The [TCMalloc Platforms Guide](docs/platforms.md) contains information on

platform support for TCMalloc.

## Documentation

All users of TCMalloc should consult the following documentation resources:

*   The [TCMalloc Quickstart](docs/quickstart.md) covers downloading,

    installing, building, and testing TCMalloc, including incorporating within

    your codebase.

*   The [TCMalloc Overview](docs/overview.md) covers the basic architecture of

    TCMalloc, and how that may affect configuration choices.

*   The [TCMalloc Reference](docs/reference.md) covers the C and C++ TCMalloc

    API endpoints.

More advanced usages of TCMalloc may find the following documentation useful:

*   The [TCMalloc Tuning Guide](docs/tuning.md) covers the configuration

    choices in more depth, and also illustrates other ways to customize

    TCMalloc. This also covers important operating system-level properties for

    improving TCMalloc performance.

*   The [TCMalloc Design Doc](docs/design.md) covers how TCMalloc works

    underneath the hood, and why certain design choices were made. Most

    developers will not need this level of implementation detail.

*   The [TCMalloc Compatibility Guide](docs/compatibility.md) which documents

    our expectations for how our APIs are used.
