// Description : An istream object that presents a subwindow into
|
|
// another istream. The first character read from this
|
|
// stream will be the "start" character from the source
|
|
// istream; just before the file pointer reaches the
|
|
// "end" character, eof is returned.
|
|
//
|
|
// The source stream must be one that we can randomly
|
|
// seek within. The resulting ISubStream will also
|
|
// support arbitrary seeks.
