Method Summary

Modifier and Type	Method	Description
MemorySegment	run(@Nullable MemorySegment data, long size)	Changes the size of the memory block pointed to by data to size bytes.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, long) method.
default MemorySegment	upcall(MemorySegment data, long size)	The upcall method is called from native code.

Method Details

run

MemorySegment run(@Nullable
 @Nullable MemorySegment data,
 long size)

Changes the size of the memory block pointed to by data to size bytes.

The function should have the same semantics as realloc().

upcall

default MemorySegment upcall(MemorySegment data,
 long size)

The upcall method is called from native code. The parameters are marshaled and run(java.lang.foreign.MemorySegment, long) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, long) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the function pointer will be allocated in this arena

Returns:

the native function pointer
