PROLOG

       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

NAME

       wmemchr - find a wide character in memory

SYNOPSIS

       #include <wchar.h>

       wchar_t *wmemchr(const wchar_t *ws, wchar_t wc, size_t n);

DESCRIPTION

       The wmemchr() function shall locate the first occurrence of wc in the initial n wide characters of the object pointed to by ws. This  func-
       tion  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 behaves as if no valid occurrence of wc is found.

RETURN VALUE

       The wmemchr() function shall return a pointer to the located wide character, or a null pointer if the wide character does not occur in  the
       object.

ERRORS

       No errors are defined.

APPLICATION USAGE

RATIONALE

       None.

FUTURE DIRECTIONS

NAME

       wmemmove - copy wide characters in memory with overlapping areas

SYNOPSIS

       #include <wchar.h>

       wchar_t *wmemmove(wchar_t *ws1, const wchar_t *ws2, size_t n);

DESCRIPTION

       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 val-
       ues 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.

RETURN VALUE

       The wmemmove() function shall return the value of ws1.

ERRORS

       No errors are defined
