WMEMMOVE(3P) POSIX Programmer's Manual WMEMMOVE(3P)
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior), or
the interface may not be implemented on Linux.
wmemmove — copy wide characters in memory with overlapping areas
#include <wchar.h>
wchar_t *wmemmove(wchar_t *ws1, const wchar_t *ws2, size_t n);
The functionality described on this reference page is aligned with
the ISO C standard. Any conflict between the requirements described
here and the ISO C standard is unintentional. This volume of
POSIX.1‐2008 defers to the ISO C standard.
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 characters 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.
