摘要： A searching method for determining a function associated with a memory block of a memory of a computer system and the computer system thereof are disclosed. A first function execution code executed by the computer system calls a second function execution code to require the computer system to allocate a first memory block to the first function execution code. A symbol mapping table (i.e., a linker map) stores a symbol address corresponding to the first function execution code. The searching method includes storing a return address of the second function execution code into a predetermined memory block of the memory, reading the return address from the predetermined memory block, and determining that the first memory block has been allocated to the first function execution code according to the return address and the symbol address stored in the symbol mapping table.
