PVOID_TO_OCTSTR

VAR_INPUT

VAR_INPUT
    in         : PVOID;
    iPrecision : INT;
END_VAR

in: The pointer variable to be converted.

iPrecision: Minimum number of displayed digits (digits). If the actual number of significant digits is less than the iPrecision parameter, the resulting string is filled with zeros from the left. If the number of significant digits is greater than the iPrecision parameter, the resulting string is not cut off! If the iPrecision parameter and the in parameter are zero, the resulting string is empty.

Example:

PROGRAM MAIN
VAR
    s1   : STRING;
    s2   : STRING;
    s3   : STRING;
    s4   : STRING;
    s5   : STRING;
    s6   : STRING;
    nCnt : WORD;
    pCnt : PVOID := 0;
END_VAR

pCnt := 0;
s1   := PVOID_TO_OCTSTR( pCnt, 0 );
s2   := PVOID_TO_OCTSTR( pCnt, 1 );
s3   := PVOID_TO_OCTSTR( pCnt, 16 );

pCnt := ADR( nCnt );
s4   := PVOID_TO_OCTSTR( pCnt, 0 );
s5   := PVOID_TO_OCTSTR( pCnt, 1 );
s6   := PVOID_TO_OCTSTR( pCnt, 16 );

The result:

s1 = ''

s2 = '0'

s3 = '0000000000000000'

s4 = '20767501125' (may vary)

s5 = '20767501125' (may vary)

s6 = '0000020767501125' (may vary)
