Reading a ^Z

Reading a ^Z

[Ian Collins]

Please help someone!

I am sure this has come up before (probably before I joined).
I am reading a binary file. The file is fopened with O_RDONLY.
When doing the read, I am using,

n = fread((void *) buffer, (size_t) sizeof(char), (size_t)
numrecs*reclen, ifd);

where numrecs and reclen are the number of records in the file each of
length reclen.

If there is a control-Z (^Z) in the file, the fread will read up to the
^Z and the rest of the buffer is filled with NULLS.
Now I know, in the distant past, DOS files were terminated by a ^Z, but
surely there is a workaround to this.
I am using b18 with Sergeys latest cygwin.dll.

Remount your filesystems with -b,
the only thing that gets opened in
text mode (recognizes ^Z and expects \r\n) after
you do that are pipes.

Geoff did the default install get changed for B19 ;^)? Please Please Please!!!!

you will need to reinstall your headers/sources/shellscripts etc.
or manually convert them to \n only.

don't forget the config files in ~/ and /etc, .bashrc 
and .bash_history passwd group etc...
