The only reason to pass a pointer to a pointer is so that the function can change the value of the original pointer that was declared in main().

>>for(i=1;i<= int_tmp;i++)
That line is incorrect. arrays are numbered 0, 1, ... Here is the correction
for(i=0; i < int_tmp; i++)
>>for(i=1;i<=N_Cell_total;i++)
From your original post in main() -- that line is also wrong for the same reason
for(i=0; i < N_Cell_total; i++)
And don't be afraid to make liberal use of white space, it make the code easier to read.
