wmemcpy()
QNX SDP8.0C Library ReferenceAPIDeveloper
Copy wide characters from one buffer to another
Synopsis:
#include <wchar.h>
wchar_t * wmemcpy( wchar_t * ws1,
const wchar_t * ws2,
size_t n );
Arguments:
- 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.
Library:
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
Description:
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.
Note:
Copying overlapping buffers isn't guaranteed to work; use
wmemmove()
to copy buffers that overlap.
Returns:
A pointer to the destination buffer (i.e., the same pointer as ws1).
