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

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.

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().
