reset_stream: Reset a Data Stream to its Beginning

Description

Resets the counter in a DSD object to the beginning or any other position in the stream.

Usage

reset_stream(dsd, pos = 1)

Arguments

dsd

An object of class DSD_ReadStream, DSD_Wrapper DSD_ScaleStream or DSD_MG.

pos

Position in the stream (the beginning of the stream is position 1).

Details

Resets the counter of the stream object. For DSD_ReadStream objects, this is done by calling seek() on the underlying connection. For DSD_Wrapper, the counter stored in the environment variable is moved back to 1.

reset_stream(replayer) 
replayer
  
# set the dsd to position 21
