* This file is an example of operating system specific wrapper functions.
* This version implements many of the functions internally, so it can be used
* to fill in missing functions from the target system C libraries.
*
* Some of the functions are using standard C library calls in order to keep
* this file in working condition to allow the functions to be tested on a
* Linux target. Please note that OS_NO_C_LIB_DEFINES needs to be defined for
* this file to work correctly. Note that these implementations are only
* examples and are not optimized for speed.
