Function Documentation

const string base64::Base64Table

(

"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"

)

this lookup table defines the base64 encoding

bool base64::decode	(	const std::string &	data,
		char	buf[],
		unsigned int	len
	)

decodes data into buf, which you need to provide the size of in len

If buf is not large enough or data is malformed, false will be returned; otherwise true

char * base64::decode

(

const std::string &

data

)

returns a pointer to a newly allocated region contained the binary data decoded from data

If data is malformed NULL will be returned

Referenced by LoadSave::checkCreator(), and LoadSave::decodeInc().

unsigned int base64::decodeSize

(

const std::string &

data

)

returns the number of bytes which will be decoded from data

Does not check data for correctness, just counts the fill characters at the end of the string

std::string base64::encode	(	char	buf[],
		unsigned int	len
	)

returns a string containing the base64 encoding of len bytes from buf

Referenced by LoadSave::encodeInc(), EventLogger::logImage(), LoadSave::saveCreator(), SegCam::sendCloseConnectionPacket(), RawCam::sendCloseConnectionPacket(), DepthCam::sendCloseConnectionPacket(), and CameraStreamBehavior::sendSensors().
