Detailed Description
PhysicsFS allocation function pointers.
(This is for limited, hardcore use. If you don't immediately see a need for it, you can probably ignore this forever.)
You create one of these structures for use with PHYSFS_setAllocator. Allocators are assumed to be reentrant by the caller; please mutex accordingly.
Allocations are always discussed in 64-bits, for future expansion...we're on the cusp of a 64-bit transition, and we'll probably be allocating 6 gigabytes like it's nothing sooner or later, and I don't want to change this again at that point. If you're on a 32-bit platform and have to downcast, it's okay to return NULL if the allocation is greater than 4 gigabytes, since you'd have to do so anyhow.

void(* PHYSFS_Allocator::Deinit) (void)
Deinitialize your allocator. Can be NULL.
void(* PHYSFS_Allocator::Free) (void *)
Free memory from Malloc or Realloc.
int(* PHYSFS_Allocator::Init) (void)
Initialize. Can be NULL. Zero on failure.
void *(* PHYSFS_Allocator::Malloc) (PHYSFS_uint64)
Allocate like malloc().
void *(* PHYSFS_Allocator::Realloc) (void *, PHYSFS_uint64)
Reallocate like realloc().
