.In rune.h
.Ft char *
.Fn mbrune "const char *string" "rune_t rune"
.Ft char *
.Fn mbrrune "const char *string" "rune_t rune"
.Ft char *
.Fn mbmb "const char *string" "char *pattern"
.Sh DESCRIPTION
.Bf Em
The
.Bx 4.4
.Dq rune
functions are obsolete and may not be supported in future releases.
.Ef
Applications should use the
.Tn ISO
C99
.Xr wcschr 3 ,
.Xr wcsrchr 3 ,
and
.Xr wcsstr 3
functions instead.
.Pp
These routines provide the corresponding functionality of
.Fn strchr ,
.Fn strrchr
and
.Fn strstr
for multibyte strings.
.Pp
The
.Fn mbrune
function locates the first occurrence of
.Fn rune
in the string pointed to by
.Fa string .
The terminating
.Dv NUL
character is considered part of the string.
If
.Fa rune
is
.Ql \e0 ,
.Fn mbrune
locates the terminating
.Ql \e0 .
.Pp
The
.Fn mbrrune
function
locates the last occurrence of
.Fa rune
in the string
.Fa string .
If
.Fa rune
is
.Ql \e0 ,
.Fn mbrune
locates the terminating
.Ql \e0 .
.Pp
The
.Fn mbmb
function locates the first occurrence of the null-terminated string
.Fa pattern
in the null-terminated string
.Fa string .
If
.Fa pattern
is the empty string,
.Fn mbmb
returns
.Fa string ;
if
.Fa pattern
occurs nowhere in
.Fa string ,
.Fn mbmb
returns
.Dv NULL ;
otherwise
.Fn mbmb
returns a pointer to the first character of the first occurrence of
.Fa pattern .
.Sh RETURN VALUES
The function
.Fn mbrune
returns a pointer to the located character, or
.Dv NULL
if the character does not appear in the string.
.Pp
The
.Fn mbrrune
function
returns a pointer to the character, or
.Dv NULL
if the character does not appear in the string.
.Pp
The
.Fn mbmb
function
returns a pointer to the
.Fa pattern ,
or
.Dv NULL
if the
.Fa pattern
does not appear in the string.
.Sh SEE ALSO
.Xr rune 3 ,
.Xr setlocale 3 ,
.Xr euc 5 ,
.Xr utf8 5
.Sh HISTORY
The
.Fn mbrune ,
.Fn mbrrune ,
and
.Fn mbmb
functions
first appeared in Plan 9 from Bell Labs as
.Fn utfrune ,
.Fn utfrrune ,
and
.Fn utfutf .

.Sh DESCRIPTION
.Bf Em
The
.Bx 4.4
.Dq rune
functions are obsolete and may not be supported in future releases.
.Ef
Applications should use the
.Tn ISO
C99
.Xr setlocale 3 ,
.Xr mbrtowc 3 ,
.Xr wcrtomb 3 ,
.Xr fgetwc 3 ,
.Xr ungetwc 3 ,
and
.Xr fputwc 3
functions instead.
.Pp
The
.Fn setrunelocale
controls the type of encoding used to represent runes as multibyte strings
as well as the properties of the runes as defined in
.In ctype.h .
The
.Fa locale
argument indicates which locale to load.
If the locale is successfully loaded,
.Dv 0
is returned, otherwise an errno value is returned to indicate the
type of error.
.Pp
The
.Fn setinvalidrune
function sets the value of the global value
.Dv _INVALID_RUNE
to be
.Fa rune .
.Pp
The
.Fn sgetrune
function tries to read a single multibyte character from
.Fa string ,
which is at most
.Fa n
bytes long.
If
.Fn sgetrune
is successful, the rune is returned.
If
.Fa result
is not
.Dv NULL ,
.Fa *result
will point to the first byte which was not converted in
.Fa string .
If the first
.Fa n
bytes of
.Fa string
do not describe a full multibyte character,
.Dv _INVALID_RUNE
is returned and
.Fa *result
will point to
.Fa string .
If there is an encoding error at the start of
.Fa string ,
.Dv _INVALID_RUNE
is returned and
.Fa *result
will point to the second character of
.Fa string .
.Pp
the
.Fn sputrune
function tries to encode
.Fa rune
as a multibyte string and store it at
.Fa string ,
but no more than
.Fa n
bytes will be stored.
If
.Fa result
is not
.Dv NULL ,
.Fa *result
will be set to point to the first byte in string following the new
multibyte character.
If
.Fa string
is
.Dv NULL ,
.Fa *result
will point to
.Dv "(char *)0 +"
.Fa x ,
where
.Fa x
is the number of bytes that would be needed to store the multibyte value.
If the multibyte character would consist of more than
.Fa n
bytes and
.Fa result
is not
.Dv NULL ,
.Fa *result
will be set to
.Dv NULL .
In all cases,
.Fn sputrune
will return the number of bytes which would be needed to store
.Fa rune
as a multibyte character.
.Pp
The
.Fn fgetrune
function operates the same as
.Fn sgetrune
with the exception that it attempts to read enough bytes from
.Fa stream
to decode a single rune.
It returns either
.Dv EOF
on end of file,
.Dv _INVALID_RUNE
on an encoding error, or the rune decoded if all went well.
.Pp
The
.Fn fungetrune
function pushes the multibyte encoding, as provided by
.Fn sputrune ,
of
.Fa rune
onto
.Fa stream
such that the next
.Fn fgetrune
call will return
.Fa rune .
It returns
.Dv EOF
if it fails and
.Dv 0
on success.
.Pp
The
.Fn fputrune
function writes the multibyte encoding of
.Fa rune ,
as provided by
.Fn sputrune ,
onto
.Fa stream .
It returns
.Dv EOF
on failure and
.Dv 0
on success.
.Sh RETURN VALUES
The
.Fn setrunelocale
function returns one of the following values:
.Bl -tag -width Er
.It Er 0
The
.Fn setrunelocale
function
was successful.
.It Bq Er EINVAL
The
.Fa locale
name was incorrect.
.It Bq Er ENOENT
The locale could not be found.
.It Bq Er EFTYPE
The file found was not a valid file.
.El
.Pp
The
.Fn sgetrune
function either returns the rune read or
.Dv _INVALID_RUNE .
The
.Fn sputrune
function returns the number of bytes needed to store
.Fa rune
as a multibyte string.

.Sy "Plan 9 from Bell Labs" .
.\"They were conceived at the San Diego 1993 Summer USENIX conference by
.\"Paul Borman of Krystal Technologies, Keith Bostic of CSRG and Andrew Hume
.\"of Bell Labs.
