[OO.org-OS4] realloc()

31 May 2005

      Hello,

I don't know what realloc() does, the code looks like this

while (size > 0) {
    interface->altsetting = realloc(interface->altsetting, sizeof(struct usb_interface_descriptor) *
(interface->num_altsetting + 1));
    if (!interface->altsetting) {
      if (usb_debug >= 1)
        fprintf(stderr, "couldn't malloc interface->altsetting\n");
      return -1;
    }
    ....
}

So I was wonder is its extend or just allocating a new block of memory?

Kind regards
