IMemoryStream.Capacity

Syntax

Capacity: Integer;

Description

The Capacity property determines capacity in bytes of memory assigned for a stream.

Example

Sub UserProc;
Var
    File1: IFileInfo;
    BinR: IBinaryReader;
    MStream: IMemoryStream;
    i: Integer;
Begin
    MStream:=New MemoryStream.Create;
    File1:=New FileInfo.Attach("c:\New_folder\1.dat");
    If File1.Exists Then
        BinR:=File1.OpenBinaryReader;
        For i:=0 To File1.Size-1 Do
            MStream.WriteByte(BinR.Stream.ReadByte);
        End For;
        i:=MStream.Capacity;
    End If;
    Dispose File1;
    Dispose MStream;
End Sub UserProc;

After executing the example the contents of the 1.dat file is read into the MStream stream that is in memory. The "i" variable contains value of memory capacity assigned for a stream.
