reinterpret_cast_uchar_to_uint16_LE()

uint16_t vpEndian::reinterpret_cast_uchar_to_uint16_LE

(

unsigned char *const

ptr

)

Reinterpret an array of unsigned char stored in a little-endian way into an uint16_t value.

Warning

Pointer must be valid and 16-bit must be correctly readable.

swap16bits()

uint16_t vpEndian::swap16bits

(

uint16_t

val

)

Swap 16 bits by shifting to the right the first byte and by shifting to the left the second byte.

swap32bits()

uint32_t vpEndian::swap32bits

(

uint32_t

val

)

Swap 32 bits by shifting to the right the first 2 bytes and by shifting to the left the last 2 bytes.

swapDouble()

double vpEndian::swapDouble

(

double

d

)

Swap a double, the union is necessary because of the representation of a double in memory in IEEE 754.

swapFloat()

float vpEndian::swapFloat

(

float

f
