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.
