This function of the ⇘ CAA_Memory.library unpacks an "ARRAY OF BYTE" in an "ARRAY OF BOOL".
abySource[0].0 -> axDestination[0]
abySource[0].1 -> axDestination[1]
...
abySource[1].0 -> axDestination[8]
...
abySource[1].7 -> axDestination[15]
...
The function copies the amount of "uiNumberOfBits" from "abySource" to "axDestination".
The function will return the number of bytes considered in "abySource".
If "pabySource", "paxDestination" or "uiNumberOfBits" are set to "0", the copying will not be carried out and the function will return "FALSE".
|
提示！ The size of the array "axDestination" has to be adjusted to the number of bits to be copied! Source and target may not overlap! |
Input:
|
pabySource |
DWORD |
Address of ARRAY OF BYTE |
|
paxDestination |
DWORD |
Address of ARRAY OF BOOL |
|
uiNumberOfBits |
UINT |
Number of bits to be copied |
Example:
abySource : ARRAY[0..2] OF BYTE := 16#32, 16#01, 16#00 ;
axDestination : ARRAY[0..9] OF BOOL ;
uiNumberofBytes := MEM.UnpackArrayOfByte(
ADR(abySource), ADR(axDestination), 10) ;
->
uiNumberofBytes = 2
axDestination[0] = FALSE
axDestination[1] = TRUE
axDestination[2] = FALSE
axDestination[3] = FALSE
axDestination[4] = TRUE
axDestination[5] = TRUE
axDestination[6] = FALSE
axDestination[7] = FALSE
axDestination[8] = TRUE
axDestination[9] = FALSE
