Package org.lwjgl.system.jemalloc

Interface ExtentDallocI

All Superinterfaces:
org.lwjgl.system.CallbackI, org.lwjgl.system.Pointer
All Known Implementing Classes:
ExtentDalloc
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface ExtentDallocI extends org.lwjgl.system.CallbackI
Instances of this interface may be set to the ExtentHooks struct.

Type

     extent_hooks_t *extent_hooks,
     void *addr,
     size_t size,
     bool committed,
     unsigned int arena_ind
 )

      Extent deallocation hook.

      An extent deallocation function conforms to the extent_dalloc_t type and deallocates an extent at given addr and size with committed/decommited memory as indicated, on behalf of arena arena_ind, returning false upon success. If the function returns true, this indicates opt-out from deallocation; the virtual memory mapping associated with the extent remains mapped, in the same commit state, and available for future use, in which case it will be automatically retained for later reuse.
