my_strcspn()

size_t my_strcspn	(	const CHARSET_INFO *	cs,
		const char *	str,
		const char *	str_end,
		const char *	reject,
		size_t	reject_length
	)

Calculate the length of the initial segment of 'str' which consists entirely of characters not in 'reject'.

Parameters

cs	Pointer to charset info.
str	Pointer to multi-byte string.
str_end	Pointer to end of multi-byte string.
reject	Pointer to start of single-byte reject string.
reject_length	Length of single-byte reject string.

Returns

Length of segment of multi-byte string that doesn't contain any character of the single-byte reject string or zero if an invalid encoding of a character of the multi-byte string is found.

Note

The reject string points to single-byte characters so it is only possible to find the first occurrence of a single-byte character. Multi-byte characters in 'str' are treated as not matching any character in the reject string. This method returns zero if an invalid encoding of any character in the string 'str' using charset 'cs' is found.
