pid

I have the pid (process identifier) of an arbitrary running process. How can I find the bundle identifier (if any) of the associated application? Here's a way that works in 10.2 and later: First call GetProcessForPID to turn the pid into a ProcessSerialNumber . Then call ProcessInformationCopyDictionary to get the bundle ID. (Added: these functions are deprecated in OS 10.9. I don't know if they still exist in the 10.10 SDK.) I've found an answer which works on 10.6 only: [[NSRunningApplication runningApplicationWithProcessIdentifier:pid] bundleIdentifier] 来源： https://stackoverflow.com

setpgid将参数pid指定进程所属的组识别码设为参数pgid指定的组识别码。如果参数pid 为0，则会用来设置目前进程的组识别码，如果参数pgid为0，则由pid指定的进程ID将用作进程组ID。一个进程只能为它自己或它的子进程设置进程组ID #include<unistd.h> int setpgid(pid_t pid,pid_t pgid); 函数作用：将pid进程的进程组ID设置成pgid，创建一个新进程组或加入一个已存在的进程组 函数性质： 性质1：一个进程只能为自己或子进程设置进程组ID，不能设置其父进程的进程组ID。 性质2：if(pid == pgid), 由pid指定的进程变成进程组长;即进程pid的进程组ID pgid=pid. 性质3：if(pid==0),将当前进程的pid作为进程组ID. 性质4：if(pgid==0),将pid作为进程组ID. 函数使用说明：一般自己调用该函数时，最好是明确指定pid和pgid，方便阅读代码流程；若想特意为之，就要会用性质 来源： https://www.cnblogs.com/hshy/p/11848230.html

On Linux ps -eLf | grep my-process-name gives a list of the threads within my process along with the TID of each thread. On OSX ps -M pid gives me the list of the threads but does not show the TID of each thread. How can I see thread TIDs under a single process from the command line? You can't see the TIDs with the ps on Mac OS as you can experience while listing all the possible column options with ps L . Anyway, if you dont mind exploring the threads as a root, you can use dtruss , which is primarily for processing syscall details, but it will at least show you the TIDs in the PID/ LWPID

今天主要介绍一下使用递归来按层级查找数据。 原理挺简单的，主要是通过父级id一级一级的循环查找子级，使用PHP循环代码也很容易实现，不过如果层级越多，PHP重复代码也越多，这时可以使用递归来实现这功能。 1、首先查出要使用的数据组成一个数组（避免递归里查询数据库，之后根据这个数组组成自己需要的数据就可以了） 比如得到如下数据： $data = [ ['id' => '1', 'pid' => '0', 'dsp' => '1'], ['id' => '2', 'pid' => '0', 'dsp' => '2'], ['id' => '3', 'pid' => '0', 'dsp' => '3'], ['id' => '4', 'pid' => '1', 'dsp' => '1-4'], ['id' => '5', 'pid' => '4', 'dsp' => '1-4-5'], ['id' => '6', 'pid' => '5', 'dsp' => '1-4-5-6'], ['id' => '7', 'pid' => '3', 'dsp' => '3-7'], ['id' => '8', 'pid' => '2', 'dsp' => '2-8'], ['id' => '9', 'pid' => '1', 'dsp' => '1-9'], ['id' => '10', 'pid'

1 找到高消耗cpu的进程，使用ProcessExplorer工具查看进程中的哪个线程cpu使用率过高 2 在ProcessExplorer中选中要查看的进程，右键选择properties，查看哪个线程频繁使用cpu 3 利用jstack命令输出运行栈信息 在cmd中输入Jstack -l pid >>123.txt pid是进程即应用的pid，123.txt是要输出的文件名字 4 将第2步查看的线程的十进制pid，转换成16进制，在123.txt中搜索，就可以看到这个线程中哪个部分在高消耗cpu 来源： CSDN 作者： liyunfei456 链接： https://blog.csdn.net/liyunfei456/article/details/100859398

I want to get a handle on the current logon session of processes whose parent is explorer.exe. If we run a process as administrator or a service it won't have a logon session. The reason I want to get the logon session is that I have a program (.exe) which I want to restrict opening when a user tries to open it via (right click on the .exe--> run as administrator) and when a user opens it via administrator we don't have a logon session associated with it whereas when a user opens it by double clicking on it, it has a logon session associated with it. I searched quite some places, but I just

I have a code that is floating around here for a while (the code is working for me): - (NSArray *) runningProcesses { //CTL_KERN，KERN_PROC,KERN_PROC_ALL int mib[4] = {CTL_KERN, KERN_PROC, KERN_PROC_ALL ,0}; size_t miblen = 4; size_t size; int st = sysctl(mib, miblen, NULL, &size, NULL, 0); struct kinfo_proc * process = NULL; struct kinfo_proc * newprocess = NULL; do { size += size / 10; newprocess = realloc(process, size); if (!newprocess) { if (process) { free(process); process = NULL; } return nil; } process = newprocess; st = sysctl(mib, miblen, process, &size, NULL, 0); } while (st == -1 &
