-/** @file
- @brief Allocation Group prototypes. An Allocation Group makes it easy to
- allocate multiple blocks of memory and free them all simultanously.
-
- An allocation group is useful for keeping track of multiple blocks
- of memory which are allocated at the same time (such as during initialization)
- and need to be deallocated at the same time. The allocation group maintains
- a list of allocated blocks, and can deallocate them all simultaneously which
- can be usefull for cleaning up after a partially initialized object fails.
-
- The allocation group implementation is built on top of the lower
- level allocation functions defined in pa_util.h
