Optional step: Set Symbol Path3, set the associated source code path (can be ignored)4. All ready, click "Debug Managed Me

After a parent process creates a child process through fork, the execution sequence of the parent process and child process cannot be controlled. you can use vfork to create or the parent process to call the wait function. For the difference between fork and vfork, refer to

Linux provides a mechanism that can be obtained if the parent process wants to know the state information at the end of the child process. The mechanism is that when each process exits, the kernel frees all the resources of the process, including open files, memory usage, and so on. However, it still retains certain in

1 Understanding process scheduling timing and process switching processes: Schedule () calls occur during interrupt processing (including clock interrupts, I/O interrupts, system calls, and exceptions), call schedule () directly, or call schedule () from the need_resched tag when returning to the user state; Kernel threads can directly call schedule () for

In Python, because of the existence of the global interpreter lock Gil, the multithreading in Python does not significantly improve the efficiency of the program (in this case, CPU-intensive), then in the processing of CPU-intensive computing, multi-process model to deal with, The multiprocessing library is available in the Python standard library to support the programming of multi-process models. The

What is the difference between the foreground process and the background process in the operating system? What is the characteristic. The background program basically does not interact with the user, the priority level is slightly lowerThe foreground program interacts with the user, requiring a higher response speed and a slightly higher priority level. Manually starting a

Linux C Programming learning-process, process, process !, Linux Programming Linux supports multiple processes at the same time, that is, the multi-Program Design in the modern operating system, which is also called scheduling each process in the linux system to occupy the cpu time. Since the time of each time slice is

1 Query Process 1 The process first checks the memory and the database cache area to see if there is a block of data that is needed. If it does not exist, proceed to step 2nd, and if it exists, proceed to step 4th. 2 If the query is started, the data block to be queried is changed and the system will locate the data block in the Undo section that protects the change, and if there is no change, the system l

. Net uses messages for inter-process communication to achieve process interoperability, and. net processes for inter-process communication Sometimes we may encounter the need to implement interoperability between two processes in some way, there are many ways, for example, you can try to let the two processes continuously monitor an external file, the file recor
