For the memory allocation purposes,
the programmer must use the following allocator interface
which is prototyped in lib/lib.h (see Main project header).
The functions are protected against low memory resulting in process abort on failure
and having the same meaning as the original without the
We mention functions like
consult lib/lib.h for details.
There is also a “small” memory allocator, intended to be used when frequently allocating small memory pieces. See the lib/smalloc.h header for interface. The implementation is in lib/smalloc.c.
