OTMemmove

Copies data from one memory location to another memory location.

C INTERFACE

void OTMemmove      (void* dest,
                     const void* src,
                     size_t nBytes)

C++ INTERFACE

None. C++ applications use the C interface to this function.

PARAMETERS

dest

A pointer to the location into which you are copying data.

src

A pointer to the location from which you are copying data.

nBytes

The number of bytes of data you want to copy.

DISCUSSION

You can use this function for all memory operations except where the source or destination locations hold uncached memory. In these cases, the Mac OS function BlockMoveDataUncached is much faster.

To move memory where the source and destination areas do not overlap, use the OTMemcpy function.
