constructor TMemoryStream.Init(

  ALimit: LongInt;

  ABlockSize: Word

);

Description

Initinstantiates a new TMemoryStreamobject. The memorystreamobject will initially allocate at least ALimitbytes memory, divided into memory blocks of size ABlockSize. The number of blocks needed to get to ALimitbytes is rounded up.

By default, the number of blocks is 1, and the size of a block is 8192. This is selected if you specify 0 as the blocksize.

For an example, see e.g TStream.CopyFrom.

Errors

If the stream cannot allocate the initial memory needed for the memory blocks, then the stream's status is set to stInitError.
