This module defines an interface for replacing the standard libc dynamic memory operations.

This facade doesn’t implement any heap structure or dynamic memory methods. It only requires that backends implements a void pw_MallocInit(); method. This function is called before static intialization, and is responsible for initializing global data structures required by the malloc implementation.

The intent of this module is to provide an interface for user-provided dynamic memory operations that is compatible with different implementations.


This module requires the following setup:

  1. Chose a pw_malloc backend, or write one yourself.

  2. If using GN build, Specify the pw_malloc_BACKEND GN build arg to point the library that provides a pw_malloc backend.

Module usage#

See backend docs for how to interact with the underlying dynamic memory operations implementation.
