Function Documentation

CRC24Hash()

static uint32_t CRC24Hash ( const uint8_t *  data, size_t  len  )

static

Definition at line 80 of file rtcm_framer.cc.

EndianSwap16()

static constexpr uint16_t EndianSwap16 ( const uint8_t *  num_ptr )

staticconstexpr

Definition at line 95 of file rtcm_framer.cc.

EndianSwap24()

HexPrintableInteger()

template<typename T >

HexPrintableIntegerInst<T> HexPrintableInteger

(

T

value

)

Wrap an integer so it will be output to a stream as its hex representation.

For example:

std::cout << HexPrintableValue((int16_t)-255) << std::endl;
std::cout << HexPrintableValue((uint32_t)255) << std::endl;
std::cout << HexPrintableValue((uint8_t)48) << std::endl;

generates the following output:

0xff01
0x000000ff
0x30 ('0')

Template Parameters

T	The type of the value parameter (inferred implicitly).

Parameters

value

The integer value to wrap.

Returns

The wrapped integer that can be used in an p1_ostream.

p1_ostream& operator<<	(	p1_ostream &	stream,
		const HexPrintableIntegerInst< T > &	obj
