They can be replaced with pointers to functions that handle incorrect checksums, or they can be filled with garbage values to make the program unstable.
它们可以替换为指针，指向生成错误校验和的函数；也可以填入垃圾代码使程序不稳定。例如；
On the first call into any of these functions, the pseudo client library populates a table of function Pointers that then point to the "real" (libc) implementations of these functions.
在第一次调用这些函数中的某个函数时，pseudo客户机库会填充一个包含函数指针的表，这些函数指针指向函数“真正的”(libc)实现。
Figure 1 shows the initial welcome panel that displays when you launch the IBM Support Assistant, with Pointers to the main functions.
