Abstract

Apparatus and method are provided for on-line replacement of a program running in a process. The apparatus and method do not require a special operating system, but instead use a few standard operating system calls (i.e, fork and exec, etc.). Therefore, the apparatus is highly portable between different operating system machine types.
