示例1: printf
//----------------------------------------------------------------------
// find_cstring_in_heap
//
// Finds a C string inside one or more currently valid malloc blocks.
//----------------------------------------------------------------------

// that is the C string passed in aligned on a 1 byte boundary

}示例2:
//----------------------------------------------------------------------
// find_block_for_address
//
// Find the malloc block that whose address range contains "addr".
//----------------------------------------------------------------------
malloc_match *

// find_pointer_in_memory
//
// Finds a pointer value inside one or more currently valid malloc
// blocks.
