QRcode* QRcode_encodeString	(	const char *	string,
		int	version,

		QRencodeMode	hint,
		int	casesensitive
	)

Create a symbol from the string.

The library automatically parses the input string and encodes in a QR Code symbol.

Warning: This function is THREAD UNSAFE when pthread is disabled.

Parameters

string	input string. It must be NUL terminated.
version	version of the symbol. If 0, the library chooses the minimum version for the given input data.
level	error correction level.
hint	tell the library how Japanese Kanji characters should be encoded. If QR_MODE_KANJI is given, the library assumes that the given string contains Shift-JIS characters and encodes them in Kanji-mode. If QR_MODE_8 is given, all of non-alphanumerical characters will be encoded as is. If you want to embed UTF-8 string, choose this. Other mode will cause EINVAL error.
casesensitive	case-sensitive(1) or not(0).

Returns: an instance of QRcode class. The version of the result QRcode may be larger than the designated version. On error, NULL is returned, and 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.
ERANGE	input data is too large.
