Thread: Storing different values of time

Hello,
I have a function which puts a timestamp into an array location.
The code is as follows:

Code:

time_t curtime;
curtime = time(NULL);
array[i] = ctime(&curtime);

The problem is that whenever I enter a new timestamp into a new array element, all the previous timestamps in the array are changed to this new value.
Why does it do this, and how would I go about fixing it?
Thanks.

first of all the ctime fucntion returns an char pointer that is a string. not an integer pointer. so when u do this

Code:

array[i] = ctime(&curtime);

the pointer is pointing to a one single element or location in your array. before that can i see you array decalration. got to see its a string or just and array of diferent datatype. if u still follwing the above style then the string should be 2D string.

if its a string then u need to store the first time and then second one has to be appened to the same string using some lib fucntion
like strcat.

Hello,
I actually have an array inside a struct...

Code:

struct foo{
...
  char *date_created;
  char *date_modified;  
};

Then in my main I initiliaze like so:
struct foo* f = (struct foo*)malloc(10*sizeof(struct foo)); to give me a struct with 10 locations...

Then in my function as previously stated I do
void fcn(struct foo** fooo)
{
   struct foo* f = *fooo;

   time_t curtime;
   curtime = time(NULL);

   f[i].date_created = ctime(&curtime); // where i is a global variable
...
}

I hope this clarifies things.
