Copies characters between buffers.
void *memcpy( void *dest, const void *src, size_t count ); wchar_t *wmemcpy( wchar_t *dest, const wchar_t *src, size_t count );
- New buffer.
- Buffer to copy from.
- Number of bytes to copy.
The value of dest.
Copies count bytes of src to dest. If the source and destination overlap, the behavior of memcpy is undefined. Use memmove to handle overlapping regions.
Security Note Make sure that the destination buffer is the same size or larger than the source buffer. For more information, see Avoiding Buffer Overruns.
