DESCRIPTION

The functions implement string manipulation operations over wide character strings. For a detailed description, refer to documents for the respective single-byte counterpart, such as memchr(3).

SEE ALSO

STANDARDS

These functions conform to ISO/IEC 9899:1999 (“ISO C99”), with the exception of wcpcpy(), wcpncpy(), wcscasecmp(), wcscasecmp_l(), wcsdup(), wcsncasecmp(), wcsncasecmp_l(), and wcsnlen(), which conform to IEEE Std 1003.1-2008 (“POSIX.1”); and wcslcat() and wcslcpy(), which are extensions.
