Hi all...I'm encountering a segmentation fault, but I can't explain it :(
I'm writing a file at receveir side in RTP.cc class, I have:
char tbuf[100];
FILE *tFile;
tFile = fopen(tbuf, "w");
fprintf(tFile,"%-16f id %-16d udp %-16d\n", Scheduler::instance().clock(),
mh->frame_pkt_id_, mh->size()-28);
and I'm getting simulation stopped with Segmentation fault(core dumped) and
my ns.exe.stackdump:
Exception: STATUS_ACCESS_VIOLATION at eip=610E1C14

If, instead writing file, I print on stdout:
printf("%-16f id %-16d udp %-16d\n", Scheduler::instance().clock(),
mh->frame_pkt_id_, mh->size()-28);
it works fine and simulation complete.
It's very urgent...can you give me any hint?
Thanks in advance!
