PHYSFS_Allocator(3)
NAME
PHYSFS_Allocator
PhysicsFS allocation function pointers.
SYNOPSIS
#include <physfs.h> Data Fields int(* Init )(void) void(* Deinit )(void) void *(* Malloc )(PHYSFS_uint64) void *(* Realloc )(void *, PHYSFS_uint64) void(* Free )(void *)
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().
