[lwip-devel] [bug #20478] memp_malloc returns bogus value on malloc failure

[Jared Grubb]

Follow-up Comment #3, bug #20478 (project lwip):

One of the comments is not correct, I think. You wrote: 

> create a linked list of memp elements, marking the first element in the
pool to be NULL, to allow us to detect pool exhaustion

If there are no elements for table i, then the memp_tab[i]=NULL. Otherwise,
the for(j) loop runs, and memp_tab[i] points to a linked list of elements of
size (MEMP_SIZE+memp_sizes[i]), where the last element in the list has its
"next" set to NULL.

Otherwise, more comments are always good!
