Detailní popis

!Purpose

Implementation of several stdio.h methods, such as printf(), sprintf() and so on. This reduces the memory footprint of the binary when using those methods, compared to the libc implementation.

!Usage

Adds stdio.c to the list of file to compile for the project. This will automatically replace libc methods by the custom ones.
