Question

   typedef struct _stats_pointer_t
    {
     char **fileNames;
     stats_t stats;
    } stats_pointer_t;

I need to fill ‘fileNames’. Basically, I need to mimic this functionality:

char *fileNames[argc - 1];
fileNames[0] = argv[0];

… but using the struct stats_pointer. So I need to declare the struct, then probably allocate memory for the array but I’m not sure if that’s necessary. Finally, I need to fill the array.

Revision: I need to declare the new struct as stats_pointer_t **sp; because I need to pass this struct as an argument to a thread later. So I tried allocating memory for the struct and then for fileNames, but Eclipse’s debugger tells me that it can’t access fileNames when its being allocated. So how can I do this with stats_pointer_t **sp; instead of stats_pointer_t sp;

Answer 1

stats_pointer_t p;

p.filenames = malloc(argc * sizeof *p.filenames);
for(int i = 0; i < argc - 1 ; i++) {
  p.filenames[i] = malloc(strlen(argv[i+1]) + 1);
  strcpy(p.filenames[i],argv[i+1]);
}
p.filenames[i] = NULL;

(And check for errors – like malloc returning NULL);
