◆ safe_read()

static ssize_t safe_read	(	int	filedes,
		void *	buffer,
		size_t	size
	)

static

Definition at line 83 of file dvbci.cpp.

Referenced by cTPDU::Read().

◆ GetLength()

static const uint8_t* GetLength	(	const uint8_t *	Data,
		int &	Length
	)

static

Parameters

Length	Gets the length field from the beginning of Data. This number is encoded into the output buffer. If the high order bit of the first byte is zero, then the remaining seven bits hold the actual length. If the high order bit is set then the remaining bits of that byte indicate how many bytes are used to hold the length. The subsequent bytes hold the actual length value.
Data	A pointer to current location for reading data.
Length	Used to store the length from the data stream.

Returns: Returns a pointer to the first byte after the length and stores the length value in Length.

Definition at line 95 of file dvbci.cpp.

◆ SetLength() [1/2]

static uint8_t* SetLength	(	uint8_t *	Data,
		int	Length
	)

static

Parameters

Length	Sets the length field at the beginning of Data. This number is encoded into the output buffer. If the length is less than 128, it is written directly into the first byte. If 128 or more, the high order bit of the first byte is set and the remaining bits indicate how many bytes are needed to hold the length. The subsequent bytes hold the actual length.
Data	A pointer to current location for writing data.
Length	A number to encode into the data stream.

Returns: Returns a pointer to the first byte after the length.

◆ SetLength() [2/2]

static void SetLength	(	std::vector< uint8_t > &	Data,

	)

static

Definition at line 145 of file dvbci.cpp.

◆ CopyString()

static char* CopyString	(	int	Length,
		const uint8_t *	Data
	)

static

Parameters

Data	Copies the string at Data.
Length	The number of bytes to copy from Data.
Data	A pointer to current location for reading data.

Returns: Returns a pointer to a newly allocated string.

Definition at line 166 of file dvbci.cpp.

Referenced by GetString(), and cCiMMI::Process().

◆ GetString()

static char* GetString	(	int &	Length,
		const uint8_t **	Data
	)

static

Parameters

	Data	Gets the string at Data. Upon return Length and Data represent the remaining data after the string has been copied off.
[in,out]	Length	The number of bytes to copy from Data. Updated for the size of the string read.
[in,out]	Data	A pointer to current location for reading data. Updated for the size of the string read.

Returns: Returns a pointer to a newly allocated string, or nullptr in case of error.
