Detailed Description

Global functions to convert data values.

This file declares functions to convert data from one representation to another, in particular from little endian to big endian (or vice-versa).

The functions are defined in a general way for each standard data type, so in principle every conceivable conversion could be done (for example, from the old VAX format to IEEE format). However, currently byte swap is the only conversion needed, so only that one is implemented.

Furthermore it contains a function to convert bool values to bits and vice-versa.

Function Documentation

◆ bitToBool()

unsigned int dp3::common::bitToBool ( void *  to,
const void *  from,
unsigned int  nvalues,
unsigned int  startbit = 0 
)

Convert bits to bools. startbit gives to first bit to use in the from buffer. It returns the number of bytes used.

◆ boolToBit()

unsigned int dp3::common::boolToBit ( void *  to,
const void *  from,
unsigned int  nvalues,
unsigned int  startbit = 0 
)

Convert bools to bits. startbit gives to first bit to use in the to buffer. It returns the number of bytes used.
