Re: [ptp-user] eclipse console eats output

[Greg Watson <g.watson@xxxxxxxxxxxx>]

Christoph,

Good point. There are a lot of factors involved in getting the output to the Eclipse console, which I won't go into here. Suffice to say that combining both buffered and un-buffered I/O in this way is bound to cause issues like this. You could try using printf or fputc instead of write to confirm.

Regards,

Greg

Greg,

 

as a matter of fact - fflush(stdout) didn't make any difference.

 

Perhaps not so surprising, as fflush(FILE *stream) is part of stdio.h and acts on stdio streams, while the string "abcdefghij" are written by POSIX write to a POSIX file handle. AFAIK the buffering that ffflush can flush happens in the stdio layer.

 

But I agree that it looks like a buffering issue, perhaps some buffering in the machinery that picks the output from the program and sends it to the eclipse console ?
