MultibyteWide-Character Conversion Functions

Wide-Character Array Functions

The standard character array-manipulation functions, such as memcpy( ), also have wide-character equivalents. They are shown in the following table. These functions use the header <wchar.h>.

Function	char Equivalent
wchar_t *wmemchr(const wchar_t *str,                                   wchar_t ch, size_t num)	memchr( )
int wmemcmp(const wchar_t *str1,                          const wchar_t *str2, size_t num)	memcmp( )
wchar_t *wmemcpy(wchar_t *str1,                                   const wchar_t *str2,                                   size_t num)	memcpy( ) In C99, str1 and str2 are qualified by restrict.
wchar_t *wmemmove(wchar_t *str1,                                      const wchar_t *str2,                                      size_t num)	memmove( )
wchar_t *wmemset(wchar_t *str, wchar_t ch,                                  size_t num)	memset( )
