hi,

when i handle a bad jpg file, like this:
eErr = GDALRasterIO(hBand, GF_Read, 0, 0, nXSize, nYSize,......)

i got this error message in console:
Premature end of JPEG file

i'm wonder where the error msg come from. because i found that: eErr == CE_None

when i use this code the code quiet the msg:
CPLPushErrorHandler( CPLQuietErrorHandler );
eErr = GDALRasterIO(hBand, GF_Read, 0, 0, nXSize, nYSize,......)

the error msg still be there.

so, my question is:
where the error msg come  from, how can i quiet it or handle it.
and how can i know the image file is bad before i process it.
