NAME

       iarray_allocate - get pointer to nth element in iarray

SYNTAX

       #include <libowfat/iarray.h>

       void* iarray_allocate(iarray* x, size_t pos);

         iarray x;
         size_t pos;
         t* p = iarray_allocate(&x,pos);

DESCRIPTION

       iarray_allocate  is  similar  to  iarray_get,  but  if the requested element is not in the
       array, the array will be resized.  If the resize fails, iarray_allocate returns  NULL  and
       leaves the array untouched.

       This  function  is safe to use in environments with multiple threads, but it can block for
       indeterminate time if other threads are reallocating the array at the same time.

       Note that it is safe to use iarray_allocate where you would otherwise use iarray_get.  The
       only reason to use iarray_get over iarray_allocate would be optimization.

RETURN VALUE

       Return  a  pointer  to  the  requested element.  If there was a memory allocation failure,
       returns NULL.
