Program Loading and Dynamic Linking

This chapter describes the object file information and system actions that create running programs. Most information here applies to all systems. Information specific to one processor resides in sections marked accordingly.

Executable and shared object files statically represent application programs. To execute such programs, the system uses the files to create dynamic program representations, or process images. A process image has segments that contain its text, data, stack, and so on. The following major sections are provided.
