Member Function Documentation

static size_t GdbPacket::decodeHexBlock ( void *  dst, const char *&  src  )

static

Decode hex-encoded data block.

Parameters

dst	buffer for decoded hex bytes (may be same as src)
src	source data, on return points to first character after hex data

Return values

size_t

number of decoded bytes

Note

Output is always smaller than input so safe to overwrite src

static void GdbPacket::encodeHexBlock ( char *  dst, const void *  src, size_t  size  )

static

Encode a value as hex characters, LSB first.

Parameters

dst	Location for output, will NOT be nul-terminated
srcData	Data bytes to encode
size	Size of source data in bytes destination buffer must have enough space for (size * 2) chars

static uint32_t GdbPacket::readHexValue ( const char *&  data )

static

Decode a variable-length hex value, MSB first.

Parameters

data	will get positioned on the end of the hex string, as far as the routine has read into it

Return values

uint32_t

decoded value

void GdbPacket::write	(	const void *	data,
		unsigned	length
	)

Output block of data exactly as given without escaping.

void GdbPacket::writeCharEscaped

(

char

c

)

Send a character, escaping if required.

void GdbPacket::writeEscaped	(	const void *	data,
		unsigned	length
	)

Send a block of data, escaping as required.

void GdbPacket::writeHexBlock	(	const void *	src,
		size_t	size
	)

Output a block of data, hex-encoded.
