Split_splitStringToQRinput()

int Split_splitStringToQRinput	(	const char *	string,
		QRinput *	input,
		QRencodeMode	hint,
		int	casesensitive
	)

Split the input string (null terminated) into QRinput.

Parameters

string	input string
hint	give QR_MODE_KANJI if the input string contains Kanji character encoded in Shift-JIS. If not, give QR_MODE_8.
casesensitive	0 for case-insensitive encoding (all alphabet characters are replaced to UPPER-CASE CHARACTERS.

Return values

0	success.
-1	an error occurred. errno is set to indicate the error. See Exceptions for the details.

Exceptions

EINVAL	invalid input object.
ENOMEM	unable to allocate memory for input objects.
