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.

Field Documentation

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().
