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