# GetPropInfos

Return a list of published properties.

## Declaration

Source position: typinfo.pp line 765

`procedure GetPropInfos(`
`TypeInfo: PTypeInfo;`
`PropList: PPropList`
`);`

## Description

GetPropInfos stores pointers to the property information of all published properties of a class with class info TypeInfo in the list pointed to by Proplist. The PropList pointer must point to a memory location that contains enough space to hold all properties of the class and its parent classes.

## Errors

No checks are done to see whether PropList points to a memory area that is big enough to hold all pointers.

## Example

    Program example12;

    { This program demonstrates the GetPropInfos function }

    uses

    Var
      O : TMyTestObject;
      PT : PTypeData;
      PI : PTypeInfo;
      I,J : Longint;
      PP : PPropList;
      prI : PPropInfo;

    begin
      O:=TMyTestObject.Create;
      PI:=O.ClassInfo;
      PT:=GetTypeData(PI);
      Writeln('Property Count : ',PT^.PropCount);
      GetMem (PP,PT^.PropCount*SizeOf(Pointer));
      GetPropInfos(PI,PP);
      For I:=0 to PT^.PropCount-1 do

        With PP^[i]^ do
          begin
          Write('Property ',i+1:3,': ',name:30);
