Re^2: PerlIO, random write file access and O

I thought sysopen can't be mixes with print/read, as buffered IO and unbuffered cannot be mixed? And I mentioned that I don't want to use syswrite

Or sysopen is not about unbuffered IO (in opposite to syswrite) ?

(Note that your code still unconditionally truncates the file each time.)

Ok, could you please example why? First file open mode is append, and second is read (read/write)

Oh, right, the append prevents the truncate. My mistake. sysopen is just a different way of getting a file handle. It has no bearing on whether you use buffered or unbuffered I/O with that handle. - tye	[reply]
