RE: Read row by row from IFS file

Stream files are just a stream of bytes. There are no rows as far as the file system is concerned. What you need to do is create your buffer large enough to hold at least one whole section up and including the CRLF. But I prefer to make the buffer as large as possible to reduce IO.

Once you have read into the buffer, you can walk the buffer extracting the rows up to the CRLF. Pointers work great for this. If you reach the end of the buffer and do not find a CRLF, you save the data from just after the last CRLF found to the end of the buffer into a secondary variable.

Then clear your buffer and perform the next read on the stream file. Lather, rinse, repeat...

at the end of each line is CRLF sign

I know how to read file as stream , but how in simple and smart way read
this file "row" by "row". Have you any example code?
