I'm no C programmer, but I think I know some basics
First of all, you'll need to compile this code, try
or
#invoke executable to read from standard input
Example:
#invoke executable to read from a file
Example:
Not sure, but I'd say it's
1. the processing of pre-defined number of fields (?) even if the actual number of fields exceeds that limit and thus producing wrong output
I don't know why, but during some testing I found out it will handle 24 fields, but fail when there are >25 fields.
2. the processing of pre-defined line length even if the actual line length exceeds that limit and thus producing wrong output
which I'd summarize as "no error checking".
Demo for "too many fields":
Demo for "too long line":

Hi everybody,
i've been googling for ages now and gotten kinda desperate... The question, however, might be rather trivial for the experts: What is it exactly, i.e. physically, the POSIX function (for a file) "lseek" does? Does it trigger some kind of synchronization on disk? Is it just for the... (4 Replies)
