# Allocators

> This sample demonstrates substituting custom memory allocation functions `mem_alloc()` and `mem_free()` for the standard C runtime heap management functions `malloc()` and `free()`.

### How to Run

> See instructions here on how to build this and other samples on your development platform. Once built, the sample can be run from the `\target\bin` directory:

>         api_sql_01_c_api_allocators

> But it is more instructive to run it in your development environment debugger, stepping through the code.
