|
This source file contains function prototypes for "private" but
|
|
useful functions defined in the "binary blob" ESP IoT RTOS SDK libraries.
|
|
|
|
For the "public" API, check the esp_common header file and the various
|
|
sub-headers it includes.
|
|
|
|
Function names here have the 'sdk_' prefix that is attached to all
|
|
binary library symbols by the esp-open-rtos build process.
|
|
|
|
This file is a part of esp-open-rtos.
