Macro Definition Documentation

OPUS_CLEAR

#define OPUS_CLEAR	(		dst,
			n
	)		(memset((dst), 0, (n)*sizeof(*(dst))))

Set n elements of dst to zero

OPUS_COPY

#define OPUS_COPY	(		dst,
			src,
			n
	)		(memcpy((dst), (src), (n)*sizeof(*(dst)) + 0*((dst)-(src)) ))

Copy n elements from src to dst. The 0* term provides compile-time type checking

OPUS_MOVE

#define OPUS_MOVE	(		dst,
			src,
			n
	)		(memmove((dst), (src), (n)*sizeof(*(dst)) + 0*((dst)-(src)) ))

Copy n elements from src to dst, allowing overlapping regions. The 0* term provides compile-time type checking
