WMEMMOVE(P) POSIX Programmer's Manual WMEMMOVE(P)
wmemmove - copy wide characters in memory with overlapping areas
wchar_t *wmemmove(wchar_t *ws1, const wchar_t *ws2, size_t n);
The wmemmove() function shall copy n wide characters from the object pointed to by ws2 to
the object pointed to by ws1. Copying shall take place as if the n wide characters from
the object pointed to by ws2 are first copied into a temporary array of n wide characters
that does not overlap the objects pointed to by ws1 or ws2, and then the n wide characters
from the temporary array are copied into the object pointed to by ws1.
This function shall not be affected by locale and all wchar_t values shall be treated
identically. The null wide character and wchar_t values not corresponding to valid charac-
ters shall not be treated specially.
If n is zero, the application shall ensure that ws1 and ws2 are valid pointers, and the
function shall copy zero wide characters.
The wmemmove() function shall return the value of ws1.
No errors are defined
