44 * This file contains declarations for doing callbacks to
45 * cfe from an application. It should be the only header
46 * needed by the application to use this library
48 * Authors: Mitch Lichtenberg, Chris Demetriou
50 ********************************************************************* */
56 * Apply customizations here for different OSes. These need to:
57 * * typedef uint64_t, int64_t, intptr_t, uintptr_t.
58 * * define cfe_strlen() if use of an existing function is desired.
59 * * define CFE_API_IMPL_NAMESPACE if API functions are to use
60 * names in the implementation namespace.
61 * Also, optionally, if the build environment does not do so automatically,
62 * CFE_API_* can be defined here as desired.
