49 * Authors: Mitch Lichtenberg, Chris Demetriou
51 ********************************************************************* */
57 * Apply customizations here for different OSes. These need to:
58 * * typedef uint64_t, int64_t, intptr_t, uintptr_t.
59 * * define cfe_strlen() if use of an existing function is desired.
60 * * define CFE_API_IMPL_NAMESPACE if API functions are to use
61 * names in the implementation namespace.
62 * Also, optionally, if the build environment does not do so automatically,
63 * CFE_API_* can be defined here as desired.
