NAME

tell - Return current access position for an open channel

SYNOPSIS

tell channelId

DESCRIPTION

Returns an integer string giving the current access position in channelId. This value returned is a byte offset that can be passed to seek in order to set the channel to a particular position. Note that this value is in terms of bytes, not characters like read. The value returned is -1 for channels that do not support seeking.
