common_types.h

osal for Vxworks,c code

/*
** Name: common_types.h
** Purpose: This include file defines basic types.
** Author : Alan Cudmore NASA/GSFC Code 582
**
** Modification History:
**   12/05/03 - P.Kutt : Removed RTEMS system header files.
**                       Removed CCSDS header typedefs; these are in ccsds.h.
**                       Removed time typedefs; these are in timeutils.h.
**                       Removed OS init modes; these are in osapiservices.h.
**                       Removed semaphore control blocks; these are internal to OS.
**   12/09/03 - P.Kutt : Added _USING_RTEMS_INCLUDES_ guard around typedef for boolean.
**   04/29/04 - P.Kutt : Removed obsolete macro definitions that don't begin with OS_
**                       and are not used by core tasks.

/******************************************************************************
**  NOTE:  The RTEMS operating system defines a typedef named 'boolean' (which
**  is an unsigned int).  When compiling a source file with RTEMS header files,
**  one should insert:
**    #define _USING_RTEMS_INCLUDES_
**  before including this file so that the definition of 'boolean' in this file
**  will be skipped.  Otherwise, one will get a compiler warning about multiple
**  declarations.
