Function Documentation

conv16to32Bits()

DWORD conv16to32Bits ( const WORD val )

inline

convert 16bits variable to 32bits

Parameters

[in]

val

- 16b value to convert

Returns

Converted value

conv16to8Bits()

BYTE conv16to8Bits ( const WORD val )

inline

convert 16bits variable to 8bits

Parameters

[in]

val

- 16b value to convert

Returns

Converted value

conv16upto32Bits()

DWORD conv16upto32Bits ( const WORD val, const BYTE nb )

inline

convert 16bits variable to 16+nb bits (32bits max)

Warning

conversion output shall not exceed 32bits (input shall strictly be unsigned 16bits)

nb shall be in range 0-16 (note that using 0 doesn't change val)

Parameters

[in]	val	- 16b value to convert
[in]	nb	- number of bits to add (16bits max)

Returns

Converted value

conv32to16Bits()

WORD conv32to16Bits ( const DWORD val )

inline

convert 32bits variable to 16bits

Parameters

[in]

val

- 32b value to convert

Returns

Converted value

conv32to64Bits()

inline

convert 32bits variable to 64bits

Parameters

[in]

val

- 32b value to convert

Returns

Converted value

conv32upto64Bits()

LWORD conv32upto64Bits ( const DWORD val, const BYTE nb )

inline

convert 32bits variable to 32+nb bits (64bits max)

Warning

conversion output shall not exceed 64bits (input shall strictly be unsigned 32bits)

nb shall be in range 0-32 (note that using 0 doesn't change val)

Parameters

[in]	val	- 32b value to convert
[in]	nb	- number of bits to add (32bits max)

Returns

Converted value

conv64to32Bits()

DWORD conv64to32Bits ( const LWORD val )

inline

[in]	nb	- number of bits to add (8bits max)

Returns

Converted value

convXtoYBits()

DWORD convXtoYBits ( const DWORD val, const BYTE from, const BYTE to )

inline

convert x bits variable to y bits (32bits max)

Warning
