  11.  * This file was created with you in mind. Lest you reinvent the wheel.
  12.  * If for some reason there is not enough wrapper add! I ask you to stick to the same style: snake_case.
  13.  * Structure names must start with "ksys_" and end with "_t".
  14.  * All wrappers must start with the "_ksys_" prefix.
  15.  * I consider it mandatory to place the wrappers in the correct order in the official documentation.
  16.  * Enjoy writing your code :)
  17.  
  18.  * Warning! The end of the file is the old definitions of function/structure names.
  19.  * They are for compatibility... Better not to use them.
