Thread: Is This Supposed To Happen? [Dynamic Memory]

I'm calling the following function:

Code:

unsigned int Test(void)
{
    char *var;
    
    var = (char*) malloc(255);
    memset((void*)var,0,254);
    
    strcpy(var,"A string.");
    
    free(var);
    
    MessageBox(NULL,var,"Data in var",MB_OK);
    
    return 0;
}

And, for some reason, even though it's been free()'d, I'm still getting this: (see attachment).

Is this supposed to happen? o_O

You can get anything and everything by using freed memory. All this means is that either (a) the memory has yet to be reassigned and/or (b) the new owner hasn't written new stuff in it yet. The memory is not trashed when freed.

Oh, that makes sense. Thanks p_o
