                    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.

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