\struct PHYSFS_Allocator \brief 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.

Fields

Init: Option<unsafe extern "C" fn() -> c_int>

< Initialize. Can be NULL. Zero on failure.

Deinit: Option<unsafe extern "C" fn()>

< Deinitialize your allocator. Can be NULL.

Malloc: Option<unsafe extern "C" fn(arg1: PHYSFS_uint64) -> *mut c_void>

< Allocate like malloc().

Realloc: Option<unsafe extern "C" fn(arg1: *mut c_void, arg2: PHYSFS_uint64) -> *mut c_void>

< Reallocate like realloc().

Free: Option<unsafe extern "C" fn(arg1: *mut c_void)>

< Free memory from Malloc or Realloc.
