Copy wide characters from one buffer to another
#include <wchar.h>
wchar_t * wmemmove( wchar_t * ws1,
const wchar_t * ws2,
size_t n );
- ws1
- A pointer to where you want the function to copy the data.
- ws2
- A pointer to the buffer that you want to copy data 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 memmove() function copies n wide characters from
the buffer pointed to by ws2
to the buffer pointed to by ws1. This function copies overlapping regions safely.
The wmemmove() function is locale-independent and treats all wchar_t values identically, even if they're null or invalid characters.
|
Use
wmemcpy()
for greater speed when copying buffers that don't overlap. |
A pointer to the destination buffer (i.e. the same pointed as ws1).
