PHYSFS_Allocator - PhysicsFS allocation function pointers.

#include <physfs.h>


int(* Init )(void)
void(* Deinit )(void)
void *(* Malloc )(PHYSFS_uint64)
void *(* Realloc )(void *, PHYSFS_uint64)
void(* Free )(void *)

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.
