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.

public int invoke(long DisInfo, long PC, long Offset, long OpSize, long InstSize, int TagType, long TagBuf)

The type for the operand information call back function.

This is called to get the symbolic information for an operand of an instruction. Typically this is from the relocation information, symbol table, etc. That block of information is saved when the disassembler context is created and passed to the call back in the DisInfo parameter. The instruction containing operand is at the PC parameter. For some instruction sets, there can be more than one operand with symbolic information. To determine the symbolic operand information for each operand, the bytes for the specific operand in the instruction are specified by the Offset parameter and its byte width is the OpSize parameter. For instructions sets with fixed widths and one symbolic operand per instruction, the Offset parameter will be zero and InstSize parameter will be the instruction width. The information is returned in TagBuf and is Triple specific with its specific information defined by the value of TagType for that Triple. If symbolic information is returned the function returns 1, otherwise it returns 0.
