Copy wide characters from one buffer to another
#include <wchar.h>
wchar_t * wmemcpy( wchar_t * ws1,
const wchar_t * ws2,
size_t n );
- ws1
- A pointer to the buffer that you want to copy the wide characters into.
- ws2
- A pointer to the buffer that you want to copy the wide characters from.
- n
- The number of wide characters to copy.
libc
Use the -l c option to
qcc
to link against this library.
This library is usually included automatically.
The wmemcpy() function copies n wide characters from the
buffer pointed to by ws2 into the buffer pointed to by
ws1.
The wmemcpy() function is locale-independent and treats all wchar_t values identically, even if they're null or invalid characters.

Copying overlapping buffers isn't guaranteed to work; use
wmemmove()
to copy buffers that overlap. |
A pointer to the destination buffer (i.e the same pointer as ws1).
