getCallInterface
Description copied from interface:CallbackI
Returns the libffi Call Interface for this callback function. [INTERNAL API]- Specified by:
getCallInterface
in interfaceCallbackI
- Returns:
- the CIF structure for this callback function
-
callback
default void callback(long ret, long args) Description copied from interface:CallbackI
The Java method that will be called from native code when the native callback function is invoked.- Specified by:
callback
in interfaceCallbackI
- Parameters:
ret
- a pointer to the memory used for the function's return value.If the function is declared as returning
void
, then this value is garbage and should not be used.Otherwise, the callback must fill the object to which this points, following the same special promotion behavior as
LibFFI.ffi_call(org.lwjgl.system.libffi.FFICIF, long, java.nio.ByteBuffer, org.lwjgl.PointerBuffer)
. That is, in most cases,ret
points to an object of exactly the size of the type specified whenCIF
was constructed. However, integral types narrower than the system register size are widened. In these cases your program may assume thatret
points to anffi_arg
object.args
- a vector of pointers to memory holding the arguments to the function
-
invoke
long invoke(long DisInfo, long ReferenceValue, long ReferenceType, long ReferencePC, long ReferenceName) The type for the symbol lookup function.This may be called by the disassembler for things like adding a comment for a PC plus a constant offset load instruction to use a symbol name instead of a load address value. It is passed the block information is saved when the disassembler context is created and the
ReferenceValue
to look up as a symbol. If no symbol is found for theReferenceValue
NULL
is returned. TheReferenceType
of the instruction is passed indirectly as is thePC
of the instruction inReferencePC
. If the output reference can be determined its type is returned indirectly inReferenceType
along withReferenceName
if any, or that is set toNULL
.
