Method Summary

Modifier and TypeMethod and Description
public default void
callback(long
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. That is, in most cases, ret points to an object of exactly the size of the type specified when CIF was constructed. However, integral types narrower than the system register size are widened. In these cases your program may assume that ret points to an ffi_arg object.

a vector of pointers to memory holding the arguments to the function

Implements org.lwjgl.system.CallbackI.callback.

public 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 the ReferenceValue NULL is returned. The ReferenceType of the instruction is passed indirectly as is the PC of the instruction in ReferencePC. If the output reference can be determined its type is returned indirectly in ReferenceType along with ReferenceName if any, or that is set to NULL.
