pid

Parts of my application are in C++ under windows. I need the process id for the current process. Any thoughts? The GetCurrentProcessId function will do this. Having grown accustomed to seeing yards and yards of code to accomplish seemingly straightforward tasks, I was pleasantly surprised at the directness of GetCurrentProcessId . Earlier today, I watched it run in a debugger, when I was following a new bit of code in a DllMain routine that combines the process ID with an embedded GUID to create a locally unique name for a mutex. Following is the entire routine, all three machine instructions.

How can I get the HWND of application, if I know the process ID? Anyone could post a sample please? I'm using MSV C++ 2010. I found Process::MainWindowHandle but I don't know how to use it. HWND g_HWND=NULL; BOOL CALLBACK EnumWindowsProcMy(HWND hwnd,LPARAM lParam) { DWORD lpdwProcessId; GetWindowThreadProcessId(hwnd,&lpdwProcessId); if(lpdwProcessId==lParam) { g_HWND=hwnd; return FALSE; } return TRUE; } EnumWindows(EnumWindowsProcMy,m_ProcessId); You can use EnumWindows and GetWindowThreadProcessId() functions as mentioned in this MSDN article . A single PID (Process ID) can be associated with

I'm writing a Python script that may or may not (depending on a bunch of things) run for a long time, and I'd like to make sure that multiple instances (started via cron) don't step on each others toes. The logical way to do this seems to be a PID-based lockfile… But I don't want to re-invent the wheel if there is already code to do this. So, is there a Python module out there which will manage the details of a PID-based lockfile? If you can use GPLv2, Mercurial has a module for that: http://bitbucket.org/mirror/mercurial/src/tip/mercurial/lock.py Example usage: from mercurial import error,

What does the Linux kernel acronyms PID, PPID, TGID stand for? I stumbled upon them at strace-pids . aldrinleal PID: Process Id PPID: Parent Process Id (the one which launched this PID) TGID: Thread Group Id see this question for more details 来源： https://stackoverflow.com/questions/14342773/meaning-of-pid-ppid-and-tgid

How to get a process name from his pid ? For example I execute cat file1.txt, but I want to figure out that cat command and its arguments since its pid in the system. Is there a struct to determine it or something similar? Any idea? There is not any general way to do this unix. Each OS has different ways to handle it and some are very hard. You mention Linux though. With Linux, the info is in the /proc filesystem. To get the command line for process id 9999, read the file /proc/9999/cmdline . On linux, you can look in /proc/ . Try typing man proc for more information. The contents of /proc/

jps jps -mvl --查看java的ps进程。 jstack 打印一个线程堆栈信息 top -H -p pid1 -> 得到占用资源大的pid2 jstack pid1 | grep "nid=0x printf "%x\n" pid2" -A 100打印后面100行（－C 打印前后100行 －B 打印前一百行） jmap jmap -dump:format=b,file=test.bin 4939 －－tomcat pid 1.top看java进程的cpu和mem是否高。记录下java pid号 2.jstack -l 9547 > 9547.stack --将1得到java pid号堆栈dump下来。 3.top -H -p 9547 -- java pid 得到该进程下cpu高的pid号 4.printf 0x%x 9054 －－将3得到的pid进行16进制。可以在2中dump下来的文件中找到相应的线程。 jmap -heap pid --查看内存 1.jmap -heap ${pid} （内存概述） 可查看当前内存配置 2.jmap -histo ${pid} （内存比对） -histo[:live] 打印每个class的实例数目,内存占用,类全名信息. VM的内部类名字开头会加上前缀”*”. 如果live子参数加上后,只统计活的对象数量.

$pid = str_replace('，',',',$pid); $pid = str_replace(' ','',$pid); $pid = str_replace(array('，', ' '), array(',', ''), $pid); 把逗号替换成英文的逗号。 把空格都移除。 来源： https://www.cnblogs.com/jiqing9006/p/11392645.html

I am having an issue where MySQL isn't starting on my QNAP NAS. I found this first by not being able to log in through phpMyAdmin - was getting error: #2002 Cannot log in to the MySQL server I then went to attempt to start mysql, as I guess this is a common issue with this, but it just gave a generic error. I went through troubleshooting the mysql.sock file and everything, changing its permissions, but nothing is working. I have rebooted my NAS many times. I eventually tried to restart mysql. In doing so I get: ERROR! MySQL manager or server PID file could not be found! I can't find anything
