- Use xmalloc instead of malloc.
-
- This implementation of the PWB library alloca() function,
- which is used to allocate space off the run-time stack so
- that it is automatically reclaimed upon procedure exit,
- was inspired by discussions with J. Q. Johnson of Cornell.
-
- It should work under any C implementation that uses an
- actual procedure stack (as opposed to a linked list of
- frames). There are some preprocessor constants that can
- be defined when compiling for your specific system, for
- improved efficiency; however, the defaults should be okay.
-
- The general concept of this implementation is to keep
- track of all alloca()-allocated blocks, and reclaim any
- that are found to be deeper in the stack than the current
- invocation. This heuristic does not reclaim storage as
- soon as it becomes invalid, but it will do so eventually.
-
- As a special case, alloca(0) reclaims storage without
- allocating any. It is a good idea to use alloca(0) in
- your main control loop, etc. to force garbage collection.
