PVOID_TO_STRING

The function converts the value of a pointer variable of type PVOID into a hexadecimal string (basis 16). The hexadecimal string has the PLC prefix: '16#'. The resolution is fixed at 8 digits in a 32-bit system and 16 digits in 64-bit system.

Return value

Name	Type	Description
PVOID_TO_STRING	T_MaxString

Inputs

VAR_INPUT
    in : PVOID;
END_VAR

Name	Type	Description
in	PVOID	The pointer variable to be converted.

Example:

PROGRAM MAIN
VAR
    s1   : STRING;
    s2   : STRING;
    nCnt : BYTE;
    p1   : POINTER TO BYTE := 0;
    p2   : POINTER TO BYTE := ADR( nCnt );
END_VAR

s1 := PVOID_TO_STRING( p1 );
s2 := PVOID_TO_STRING( p2 );

The result on a 32-bit system:

s1 = '16#00000000'

s2 = ''16#87DE0255' (may vary)

The result on a 64-bit system:

s1 = '16#0000000000000000'

s2 = ''16#8734651087DE0255' (may vary)
