MBRUNE(3)                               BSD Library Functions Manual                               MBRUNE(3)

NAME
     mbrune, mbrrune, mbmb -- multibyte rune support for C

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <rune.h>

     char *
     mbrune(const char *string, rune_t rune);

     char *
     mbrrune(const char *string, rune_t rune);

     char *
     mbmb(const char *string, char *pattern);

DESCRIPTION
     The 4.4BSD ``rune'' functions have been deprecated in favour of the ISO C99 extended multibyte and wide
     character facilities and should not be used in new applications.  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 multi-byte multibyte
     byte 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 ter-minating terminating
     minating `\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-ter-minated null-terminated
     minated 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.

RETURN VALUES
     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.

HISTORY
     The mbrune(), mbrrune(), and mbmb() functions first appeared in Plan 9 from Bell Labs as utfrune(),
     utfrrune(), and utfutf().
