HI everybody.
I'm having a problem writing a multi-threaded application.
As I understand from the mans, calls to read and write are synchronized through
file-locks. Having looked through the source for libc_r I noticed that calls to printf
and fprintf are also synchronized.
The question is - why I am still having a problem calling fprintf(stderr, ... from
multiple threads, the output is simply not written until I make a socond or a third
call to fprintf.
I have disabled buffering for stderr with setvbuf.
Thank you in advance.
