Hi folks,
while writing an open_capture_file() function for lua I came up with
an odd situation.
When executing the following code more than once, during the cf_read
call the stack gets overwritten.
if (cf_open(&cfile, fname, FALSE, &err) != CF_OK) {
return FALSE;
}
cfile.rfcode = rfcode;
switch (cf_read(&cfile)) {
case CF_READ_OK:
case CF_READ_ERROR:
break;
default:
return FALSE;
}
overwriting happens when calling wtap_read() from file.c:405
I tried to understand why this happens but nothing appears to me to be
the cause.
Is there something I should do before calling cf_open() to avoid this happening.
Thanks,
Luis
