* @file lib_printf.c
|
|
*
|
|
* This file contains library-specific printf functions
|
|
* used by WiFi libraries in the `lib` directory.
|
|
* These function are used to catch any output which gets printed
|
|
* by libraries, and redirect it to ESP_LOG macros.
|
|
*
|
|
* Eventually WiFi libraries will use ESP_LOG functions internally
|
|
* and these definitions will be removed.
