PtrInt

The data types ptrInt (“Peter Int”) and ptrUInt (“Pee true Int”) are signed and unsigned integer data types respectively having the same sizeOf of a pointer.

application

• Use ptrUInt if an integer value will eventually be typecasted to a pointer.
• Regardless of the size taken up by its elements, an array cannot have more than high(ptrInt) elements. Additionally, the range type must be a subrange of ptrInt.¹

notes

• PtrInt/ptrUInt are not necessarily the same size of ALUSInt/ALUUInt.
• The introduction of ptrInt was a mistake. New code should not use it.
• IntPtr and nativeInt are aliases for ptrInt.
• UIntPtr and nativeUInt are aliases for ptrUInt.
• PtrInt and ptrUInt are redefined by the unit unicodeData.
