# NewStr

Allocate a copy of a shortstring on the heap.

## Declaration

Source position: objects.pp line 620

`function NewStr(`
`const S: string`
`):PString;`

## Description

NewStr makes a copy of the string S on the heap, and returns a pointer to this copy. If the string is empty then Nil is returned.

The allocated memory is not based on the declared size of the string passed to NewStr, but is baed on the actual length of the string.

## Errors

If not enough memory is available, an 'out of memory' error will occur.

## See also

## Example

    Program ex40;

    { Program to demonstrate the NewStr function }

    Uses Objects;

    Var S : String;
        P : PString;

    begin
      S:='Some really cute string';
      P:=NewStr(S);
      If P^<>S then
        Writeln ('Oh-oh... Something is wrong !!');
      DisposeStr(P);
    end.
