28. Process Creation and Program Execution in More Detail

Chapter 28. Process Creation and Program Execution in More Detail

This chapter extends the material presented in Chapter 24 to Chapter 27 by covering a variety of topics related to process creation and program execution. We describe process accounting, a kernel feature that writes an accounting record for each process on the system as it terminates. We then look at the Linux-specific clone() system call, which is the low-level API that is used to create threads on Linux. We follow this with some comparisons of the performance of fork(), vfork(), and clone(). We conclude with a summary of the effects of fork() and exec() on the attributes of a process.
