static Rnc* Syndicate::Data::Rnc::getInstance

(

void

)

[static]

Get an unique instance of the class.

uint8_t* Syndicate::Data::Rnc::unpack	(	uint8_t *	input,
		unsigned &	output_length
	)			const

Unpack the given byte array.

Parameters:

[in]	input	is the compressed data array.
[out]	output_length	is the uncompressed length

Returns:

a pointer to the decompressed data or zero if it fails.

Warning:

The returned pointer must be freed by the user.

bool Syndicate::Data::Rnc::isRnc

(

uint8_t *

input

)

const

Identify a data array as compressed or not.

Parameters:

[in]

input

is a buffer to test.

Returns:

true if the buffer is RNC compressed.

uint16_t Syndicate::Data::Rnc::crc	(	uint8_t const *	data,
		unsigned	len
	)			const [private]

Compute the CRC of a buffer
