fgetl, textscan, and the file position indicator

Asked by per isakson on 7 Sep 2012

Is a construct like this legal?

It doen't return any error, but the "file position indicator" is not advanced as it should. I read a text file CRLF for new line.

    fid = fopen( ... );
    str = fgetl( fid );
    cac = textscan( fid, ... );
    str = fgetl( fid );
    cac = textscan( fid, ... );
    fclose( fid )

That series is valid, yes.

Did you open the file with 'rt' instead of 'r' in order to account for the CRLF ?

Also note that if you use a count for textscan() then the file position will be left after the last format code is used, before the newline for that line (unless the end of format matches newline)
