wmemstring(3S)wmemstring(3S)NAME
wmemstring: wmemchr, wmemcmp, wmemcpy, wmemmove, wmemset - wide character
array functions
SYNOPSIS
#include <wchar.h>
wchar_t *wmemchr (const wchar_t *s, wchar_t c, size_t n);
int wmemcmp (const wchar_t *s1, const wchar_t *s2, size_t n);
wchar_t *wmemcpy (wchar_t *s1, const wchar_t *s2, size_t n);
wchar_t *wmemmove (wchar_t *s1, const wchar_t *s2, size_t n);
wchar_t *wmemset (wchar_t *s, const wchar_t c, size_t n);
DESCRIPTION
The wmemchr function finds the location of the first occurrence of c wide
character in the initial n wide characters of the wide character string
object pointed to by s. The function returns a pointer to the located
wide character, or it returns a null pointer if it does not encounter the
wide character in the wide character string object.
The wmemcmp function compares the first n wide characters of the wide
character string object pointed to by s1 to the first n wide characters
of the wide character string object pointed to by s2. The function
returns an integer greater than, equal to, or less than zero, accordingly
as the wide character string object pointed to by s1 is greater than,
equal to, or less than the wide character string object pointed to by s2.
The wmemcpy function copies n wide characters from the wide character
string object pointed to by s2 to the wide character string object
pointed to by s1. The function returns the value of s1.
The wmemmove function copies n wide characters from the wide character
string object pointed to by s2 to the wide character string object
pointed to by s1. Even if the two wide character strings are overlapped,
the wide character string object pointed to by s2 is copied to the wide
character string object pointed to by s1 correctly. The function returns
the value of s1.
The wmemset function copies the wide character value of c into each of
the first n wide characters of the wide character string object pointed
to by s. The function returns the value of s.
NOTES
Those functions are supported in n32 and 64 bit C Libraries for IRIX
6.5.17 and later versions.
