It works.

Hi Ankit,
By restore I’m assuming you mean that DMTCP should restore the deleted
file to
the state it was in at the time of checkpoint. If yes, then you could
try using
the --ckpt-open-files flag with dmtcp_launch. This should save a copy
of all the
files open at the time of checkpoint, and then restores them on
restart, even if
they were deleted.
Thanks,
Rohan

Hi,
I guess it will not work. I tried the following code segment
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <unistd.h>
#include "dmtcp.h"
int main(int argc, char *argv[])
{
FILE *fp = fopen("msg", "r");
printf("Hello world \n");
char buff[256];
//char s[100];
int s = 0;
//memset(s, 1, sizeof(s));
while(1)
{
sleep(1);
printf("S == %d\n", s);
s++;
if(fgets(buff, 256, fp) != NULL)
printf("Read value = %s\n", buff);
if(s == 8)
{
if (*dmtcp_checkpoint*() != DMTCP_AFTER_CHECKPOINT)
printf("Checkpoint Not successful\n");
else
printf("Hurray \n");
}
if(s == 20)
{
*unlink*("msg");
exit(0);
}
}
}
I got following error on restart
./dmtcp_restart_script.sh
*[43000] ERROR at fileconnection.cpp:708 in refill;
REASON='JASSERT(jalib::Filesystem::FileExists(_path)) failed'
_path = msg*
Message: File not found.
a.out (43000): Terminating...
Is there a way above can work ?

Hi,
I want ask whether following application can restored using dmtcp.
Consider an application which reads contents from some file and then
takes checkpoint in between using *dmtcp_checkpoint* API interface.
Now if the end of application this files gets deleted, would
restore still work from checkpoint database ?
