+/// A #xed_disassembly_callback_fn_t takes an address, a pointer to a
+/// symbol buffer of buffer_length bytes, and a pointer to an offset. The
+/// function fills in the symbol_buffer and sets the offset to the desired
+/// offset for that symbol.  If the function succeeds, it returns 1. 
+//  The call back should return 0 if the buffer is not long enough to
+//  include the null termination.If no symbolic information is
+//  located, the function returns zero.
+///  @param address The input address for which we want symbolic name and offset
+///  @param symbol_buffer A buffer to hold the symbol name. The callback function should fill this in and terminate
+///                       with a null byte.
+///  @param buffer_length The maximum length of the symbol_buffer including then null
+///  @param offset A pointer to a xed_uint64_t to old the offset from the provided symbol.
+///  @param context This void* pointer passed to the disassembler's new interface so that the caller can identify 
+///                     the proper context against which to resolve the symbols. 
+///                     The disassembler passes this value to
+///                     the callback. The legacy formatters
