## Detailed Description

This section describes the base class used for initializing the encoder / decoder requests and the XED library initialization function.

All XED functions reside in the XED namespace. To use XED, you must include "xed-interface.h" and then use the name space:

        #include "xed-interface.h"

If you are calling XED2 from C++, you must wrap this include:

        extern "C" {
        #include "xed-interface.h"
        }

Once, before using XED, you must call xed_tables_init() to initialize the tables XED uses for encoding and decoding:

        xed_tables_init();

Once initialized, XED is reentrant (multithread safe). All values used for encoding and decoding live on the caller's stack or in the passed-in parameters.

If your program is multithreaded, initialize XED once (and only once) using the above call before you attempt to decode or encode from any thread. Each thread does NOT need to initialize XED. The idea is to initialize XED before creating your threads.

The same goes for the xed_register_disassembly_callback() if you are using it as described in section Printing (disassembling) Instructions.

If you are using the decode cache, you must allocate per-thread caches as described in section Using the decode cache.

## Typedef Documentation

typedef struct xed_state_s xed_state_t

| Encapsulates machine modes for decoder/encoder requests. It specifies the machine operating mode as a xed_machine_mode_enum_t for decoding and encoding. The machine mode corresponds to the default data operand width for that mode. For all modes other than the 64b long mode (XED_MACHINE_MODE_LONG_64), a default addressing width, and a stack addressing width must be supplied of type xed_address_width_enum_t .

## Function Documentation

XED_DLL_EXPORT char const* xed_get_copyright | ( | void |  | ) |

| Returns a copyright string.

XED_DLL_EXPORT char const* xed_get_version | ( | void |  | ) |

| Returns a string representing XED svn commit revision and time stamp.

XED_DLL_EXPORT void xed_register_abort_function | ( | xed_user_abort_function_t | fn,
|  | void * | other
| ) |

| This is for registering a function to be called during XED's assert processing. If you do not register an abort function, then the system's abort function will be called. If your supplied function returns, then abort() will still be called.

Parameters:

  | fn | This is a function pointer for a function that should handle the assertion reporting. The function pointer points to a function that takes 4 arguments: (1) msg, the assertion message, (2) file, the file name, (3) line, the line number (as an integer), and (4) other, a void pointer that is supplied as thei 2nd argument to this registration.
  | other | This is a void* that is passed back to your supplied function fn as its 4th argument. It can be zero if you don't need this feature. You can used this to convey whatever additional context to your assertion handler (like FILE* pointers etc.).

|  | xed_address_width_enum_t | arg_stack_addr_width
| ) | `[static]`

| Constructor. DEPRECATED: use xed_state_init2(). The mode, and addresses widths are enumerations that specify the number of bits. In 64b mode (XED_MACHINE_MODE_LONG_64) the address width and stack address widths are 64b (XED_ADDRESS_WIDTH_64b). In other machine modes, you must specify valid addressing widths.

Parameters:

  | p | the pointer to the xed_state_t type
  | arg_mmode | the machine mode of type xed_machine_mode_enum_t
  | arg_ignored | Ignored. The addressing width is now implied by the machine mode implied by arg_mmmode.
  | arg_stack_addr_width | the stack address width of type xed_address_width_enum_t (only required if not the mode is not XED_MACHINE_MODE_LONG_64)

| Constructor. The mode, and addresses widths are enumerations that specify the number of bits. In 64b mode (XED_MACHINE_MODE_LONG_64) the address width and stack address widths are 64b (XED_ADDRESS_WIDTH_64b). In other machine modes, you must specify valid addressing widths.

  | arg_mmode | the machine mode of type xed_machine_mode_enum_t
  | arg_stack_addr_width | the stack address width of type xed_address_width_enum_t (only required if not the mode is not XED_MACHINE_MODE_LONG_64)
