A process can consist of multiple LWPs and multiple application threads. The kernel schedules a kernel-thread structure, which is the scheduling entity in the SunOS environment. Various process structures are described in the following table.
Table 5-2 Process Structures
|
The following figure illustrates the relationships among these process structures.
Figure 5-1 Relationships Among Process Structures
Most process resources are accessible to all the threads in the process. Almost all process virtual memory is shared. A change in shared data by one thread is available to the other threads in the process.
