utf8strirchr()

Search backwards for a UTF-8 character in a string, ignoring case

Synopsis:

char *utf8strirchr( char const *string_base, 
                    char const *start_char, 
                    char const *mbchar, 
                    int *count );

Arguments:

string_base

A pointer to the beginning of the string to search.

start_char

A pointer to the character in the string from which to search.

mbchar

The character to look for.

count

A pointer to the location where utf8strirchr() stores the number of characters spanned to find mbchar.

Library:

ph

Description:

The utf8strirchr() function searches backwards from start_char to string_base, inclusive, for a character that matches mbchar, regardless of case. If such a match occurs, count (if provided) is set to the number of characters spanned to find the match.

Returns:

A pointer to the beginning of the matching character within string_base, or NULL if no match is found.
