* fake EOI marker is the best course of action --- this will allow the

|

|
*
|
||||||
|
* In applications that need to be able to suspend compression due to input
|
||||||
|
* not being available yet, a FALSE return indicates that no more data can be
|
||||||
|
* obtained right now, but more may be forthcoming later. In this situation,
|
||||||
|
* the decompressor will return to its caller (with an indication of the
|
||||||
|
* number of scanlines it has read, if any). The application should resume
|
||||||
|
* decompression after it has loaded more data into the input buffer. Note
|
||||||
|
* that there are substantial restrictions on the use of suspension --- see
|
||||||
|
* the documentation.
|
||||||
|
*
|
||||||
|
* When suspending, the decompressor will back up to a convenient restart point
|
||||||
|
* (typically the start of the current MCU). next_input_byte & bytes_in_buffer
|
||||||
|
* indicate where the restart point will be if the current call returns FALSE.
|
||||||
|
* Data beyond this point must be rescanned after resumption, so move it to
|
||||||
|
* the front of the buffer rather than discarding it.
