Bool_t BufferIO::Copy ( const Char_t *  from, UInt_t  from_size  )

virtualinherited

copy an external buffer to this.

It works the same way than Link and thus propose a safer method (a external buffer may be deleted or modified during the processing of that one)

As a consequence:

• switch to inner buffer (in case you don't want this, use Import/Export methods instead)
• It starts the copy from the beginning in the destination buffer
• Try to expand if the current size in too small.
• Offset is set to 0 (beginning of the buffer)
