2 | FUNCTION |
---|
3 | <<wmemmove>>---copy wide characters in memory with overlapping areas |
---|
4 | |
---|
5 | SYNOPSIS |
---|
6 | #include <wchar.h> |
---|
7 | wchar_t *wmemmove(wchar_t *<[d]>, const wchar_t *<[s]>, size_t <[n]>); |
---|
8 | |
---|
9 | DESCRIPTION |
---|
10 | The <<wmemmove>> function copies <[n]> wide characters from the object |
---|
11 | pointed to by <[s]> to the object pointed to by <[d]>. Copying takes |
---|
12 | place as if the <[n]> wide characters from the object pointed to by |
---|
13 | <[s]> are first copied into a temporary array of <[n]> wide characters |
---|
14 | that does not overlap the objects pointed to by <[d]> or <[s]>, and then |
---|
15 | the <[n]> wide characters from the temporary array are copied into the |
---|
16 | object pointed to by <[d]>. |
---|
17 | |
---|
18 | This function is not affected by locale and all wchar_t values are |
---|
19 | treated identically. The null wide character and wchar_t values not |
---|
20 | corresponding to valid characters are not treated specially. |
---|
21 | |
---|
22 | If <[n]> is zero, <[d]> and <[s]> must be a valid pointers, and the |
---|
23 | function copies zero wide characters. |
---|
24 | |
---|
25 | RETURNS |
---|
26 | The <<wmemmove>> function returns the value of <[d]>. |
---|
27 | |
---|
28 | PORTABILITY |
---|
29 | <<wmemmove>> is ISO/IEC 9899/AMD1:1995 (ISO C). |
---|
30 | |
---|
31 | No supporting OS subroutines are required. |
