/**
|
|
* @file UnicodeMain.h
|
|
* @brief Declaration of unicode entry point (umain())
|
|
* @author Jack (jakcron)
|
|
* @version 0.1
|
|
* @date 2020/04/13
|
|
* @details
|
|
* Including UnicodeMain.h bootstraps @ref umain() by defining the platform specific unicode entry point.
|
|
*
|
|
* You must define @ref umain() as your entry point if you include this header. Compiler errors will occur if you define any other entrypoints or do not define @ref umain().
