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

memchr(3), memcmp(3), memcpy(3), memmove(3), memset(3), stpcpy(3), stpncpy(3), strcasecmp(3), strcat(3), strchr(3), strcmp(3), strcpy(3), strcspn(3), strdup(3), strlcat(3), strlcpy(3), strlen(3), strncat(3), strncmp(3), strncpy(3), strnlen(3), strpbrk(3), strrchr(3), strspn(3), strstr(3)

STANDARDS

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