ISAType GetCurrentISA (void);

DESCRIPTION

can return.

SPECIAL CONSIDERATIONS

Currently, the GetCurrentISA function is defined as a compiler macro.

#if defined(powerc) || defined(__powerc)
#define GetCurrentISA()       ((ISAType) kPowerPCISA)
#else
#define GetCurrentISA()       ((ISAType) kM68kISA)
#endif
