* CPU_SW_EXCEPTION()
*
* Description : Trap unrecoverable software exception.
*
* Argument(s) : err_rtn_val Error type &/or value of the calling function to return (see Note #2b).
*
* Return(s) : none.
*
* Note(s) : (1) CPU_SW_EXCEPTION() deadlocks the current code execution -- whether multi-tasked/
* -processed/-threaded or single-threaded -- when the current code execution cannot
* gracefully recover or report a fault or exception condition.
*
* Example CPU_SW_EXCEPTION() call :
*
* void Fnct (CPU_ERR *p_err)
* {
* :
*
* if (p_err == (CPU_ERR *)0) { If 'p_err' NULL, cannot return error ...
* CPU_SW_EXCEPTION(;); ... so trap invalid argument exception.
* }
*
* :
* }
*
* See also 'cpu_core.c CPU_SW_Exception() Note #1'.
*
* (2) (a) CPU_SW_EXCEPTION() MAY be developer-implemented to output &/or handle any error or
* exception conditions; but since CPU_SW_EXCEPTION() is intended to trap unrecoverable
* software conditions, it is recommended that developer-implemented versions prevent
* execution of any code following calls to CPU_SW_EXCEPTION() by deadlocking the code
* (see Note #1).
*
* Example CPU_SW_EXCEPTION() :
*
* #define CPU_SW_EXCEPTION(err_rtn_val) do { \
* Log(__FILE__, __LINE__); \
* CPU_SW_Exception(); \
* } while (0)
*
* (b) (1) However, if execution of code following calls to CPU_SW_EXCEPTION() is required
* (e.g. for automated testing); it is recommended that the last statement in
* developer-implemented versions be to return from the current function to prevent
* possible software exception(s) in the current function from triggering CPU &/or
* hardware exception(s).
*
* Example CPU_SW_EXCEPTION() :
*
* #define CPU_SW_EXCEPTION(err_rtn_val) do { \
* Log(__FILE__, __LINE__); \
* return err_rtn_val; \
* } while (0)
*
* (A) Note that 'err_rtn_val' in the return statement MUST NOT be enclosed in
* parentheses. This allows CPU_SW_EXCEPTION() to return from functions that
* return 'void', i.e. NO return type or value (see also Note #2b2A).
*
* (2) In order for CPU_SW_EXCEPTION() to return from functions with various return
* types/values, each caller function MUST pass an appropriate error return type
* & value to CPU_SW_EXCEPTION().
*
* (A) Note that CPU_SW_EXCEPTION() MUST NOT be passed any return type or value
* for functions that return 'void', i.e. NO return type or value; but SHOULD
* instead be passed a single semicolon. This prevents possible compiler
* warnings that CPU_SW_EXCEPTION() is passed too few arguments. However,
* the compiler may warn that CPU_SW_EXCEPTION() does NOT prevent creating
* null statements on lines with NO other code statements.
*
* Example CPU_SW_EXCEPTION() calls :
*
* void Fnct (CPU_ERR *p_err)
* {
* :
*
* if (p_err == (CPU_ERR *)0) {
* CPU_SW_EXCEPTION(;); Exception macro returns NO value
* } (see Note #2b2A)
*
* :
* }
*
* CPU_BOOLEAN Fnct (CPU_ERR *p_err)
* {
* :
*
* if (p_err == (CPU_ERR *)0) {
* CPU_SW_EXCEPTION(DEF_FAIL); Exception macro returns 'DEF_FAIL'
* }
*
* :
* }
*
* OBJ *Fnct (CPU_ERR *p_err)
* {
* :
*
* if (p_err == (CPU_ERR *)0) {
* CPU_SW_EXCEPTION((OBJ *)0); Exception macro returns NULL 'OBJ *'
* }
*
* :
* }

* char_2 2nd ASCII character to create generic type value.
*
* char_3 3rd ASCII character to create generic type value.
*
* char_4 4th ASCII character to create generic type value.
*
* Return(s) : 32-bit generic type value.
*
* Note(s) : (1) (a) Generic type values should be #define'd with large, non-trivial values to trap
* & discard invalid/corrupted objects based on type value.
*
* In other words, by assigning large, non-trivial values to valid objects' type
* fields; the likelihood that an object with an unassigned &/or corrupted type
* field will contain a value is highly improbable & therefore the object itself
* will be trapped as invalid.
*
* (b) (1) CPU_TYPE_CREATE() creates a 32-bit type value from four values.
*
* (2) Ideally, generic type values SHOULD be created from 'CPU_CHAR' characters to
* represent ASCII string abbreviations of the specific object types. Memory
* displays of object type values will display the specific object types with
* their chosen ASCII names.
*
* Examples :
*
* #define FILE_TYPE CPU_TYPE_CREATE('F', 'I', 'L', 'E')
* #define BUF_TYPE CPU_TYPE_CREATE('B', 'U', 'F', ' ')
