DESCRIPTION

     These functions implement string manipulation operations over wide-char-
     acter strings.  For a detailed description, refer to the documents for
     the respective single-byte counterpart, such as memchr(3).  The wcswcs()
     function is not a part of ISO/IEC 9899:1990 (``ISO C90'') and ISO/IEC
     9899/AMD1:1995 (``ISO C90, Amendment 1''), the wcsstr() function is
     strongly recommended to be used.

     stpncpy(3), strcasecmp(3), strcat(3), strchr(3), strcmp(3), strcpy(3),
     strcspn(3), strdup(3), strlcat(3), strlcpy(3), strlen(3), strncat(3),

     strstr(3)


STANDARDS

     These functions conform to ISO/IEC 9899:1999 (``ISO C99'') and were first
     introduced in ISO/IEC 9899/AMD1:1995 (``ISO C90, Amendment 1''), with the
     exception of wcslcat() and wcslcpy(), which are extensions.  The wcswcs()
     function conforms to X/Open Portability Guide Issue 4, Version 2
     (``XPG4.2'').
