All definitions are prefixed with \b os to give an unique name space for CMSIS-RTOS functions.
Definitions that are prefixed \b os_ are not used in the application code but local to this header file.
All definitions and functions that belong to a module are grouped and have a common prefix, i.e. \b osThread.
