Dear allan:
Execue me, I have a question to ask for help:
--->Does the SANE backend provide an extension of the error message for
developers ?
The next information is extract from sane.h.
typedef enum
{
SANE_STATUS_GOOD = 0, /* everything A-OK */
SANE_STATUS_UNSUPPORTED, /* operation is not supported */
SANE_STATUS_CANCELLED, /* operation was cancelled */
SANE_STATUS_DEVICE_BUSY, /* device is busy; try again later */
SANE_STATUS_INVAL, /* data is invalid (includes no dev at open) */
SANE_STATUS_EOF, /* no more data available (end-of-file) */
SANE_STATUS_JAMMED, /* document feeder jammed */
SANE_STATUS_NO_DOCS, /* document feeder out of documents */
SANE_STATUS_COVER_OPEN, /* scanner cover is open */
SANE_STATUS_IO_ERROR, /* error during device I/O */
SANE_STATUS_NO_MEM, /* out of memory */
SANE_STATUS_ACCESS_DENIED /* access to resource has been denied */
}
SANE_Status;
Look forward to your help, Thank you very much.
Best Regard
Yours Sincerely, Yihao
