PROLOG

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.

NAME

wmemset — set wide characters in memory

SYNOPSIS

  #include <wchar.h>
  wchar_t *wmemset(wchar_t *ws, wchar_t wc, size_t n);

DESCRIPTION

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.

The wmemset/() function shall copy the value of /wc into each of the first n wide characters of the object pointed to by ws. 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 ws is a valid pointer, and the function shall copy zero wide characters.

RETURN VALUE

The wmemset/() functions shall return the value of /ws.
