Consider working with wide characters instead, and using wcschr(3), wcsrchr(3), and wcsstr(3) instead of these functions.
These routines provide the corresponding functionality
of strchr
(),
strrchr
()
and
strstr
()
for multibyte strings.
The
mbrune
()
function locates the first occurrence of
rune
()
in the string pointed to by string. The terminating
NUL
character is considered part of the string. If
rune is ‘\0
’,
mbrune
() locates the terminating
‘\0
’.
The
mbrrune
()
function locates the last occurrence of rune in the
string string. If rune is
‘\0
’, mbrune
()
locates the terminating ‘\0
’.
The
mbmb
()
function locates the first occurrence of the null-terminated string
pattern in the null-terminated string
string. If pattern is the empty
string, mbmb
() returns string;
if pattern occurs nowhere in
string, mbmb
() returns
NULL
; otherwise mbmb
()
returns a pointer to the first character of the first occurrence of
pattern.
The function mbrune
() returns a pointer to
the located character, or NULL
if the character does
not appear in the string.
The mbrrune
() function returns a pointer
to the character, or NULL
if the character does not
appear in the string.
The mbmb
() function returns a pointer to
the pattern, or NULL
if the
pattern does not appear in the string.
The mbrune
(),
mbrrune
(), and mbmb
()
functions first appeared in Plan 9 from Bell Labs as
utfrune
(), utfrrune
(), and
utfutf
().
