WMEMCPY(3P) POSIX Programmer's ManualWMEMCPY(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.
wmemcpy — copy wide characters in memory
#include <wchar.h> wchar_t *wmemcpy(wchar_t *restrictws1, const wchar_t *restrictws2, size_tn);
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.1‐2017 defers to the ISO C standard. Thewmemcpy() function shall copyn wide characters from the object pointed to byws2 to the object pointed to byws1. This function shall not be affected by locale and allwchar_tvalues shall be treated identically. The null wide character andwchar_t values not corresponding to valid characters shall not be treated specially. Ifn is zero, the application shall ensure thatws1 andws2 are valid pointers, and the function shall copy zero wide characters.
Thewmemcpy() function shall return the value ofws1.
