1：通过联盟下载的excel订单，可以看出每一个订单的唯一标识符有两个 (1). 订单号 (2). pid推广位 2：订单号在用户那里无法自动获取，区分订单方式 (1). 让用户提交订单号（体验效果不好） (2). 给用户绑定一个pid（推荐） 3：目前联盟可以创建pid，上万个（具体多少没有统计） (1). 提前创建好pid 1万个插入数据库（可以借助软件），当用户注册的时候，随机分配一个pid进行绑定 (2). 然后通过转链API接口，生成当前用户pid的推广链接，当用户购买以后，就会产生对应的pid订单， (3). 将联盟订单时时同步倒是数据库（可以借助软件30秒同步一次，1分钟同步一次） (4). 根据用户当前pid，查询对应订单 4：用到的技术 (1). 转链高佣金API（官方API，高级权限） (2). 订单同步软件(或者官方API，高级权限) http://open.taobao.com/api.htm?docId=38078&docType=2 5：pid创建软件（目前没有API,模拟请求创建）来源： CSDN 作者： API技术爱好者链接： https://blog.csdn.net/Andyfu2019/article/details/103508255

How do I inform a user space application that the driver has received an interrupt in linux?

阅读更多关于 How do I inform a user space application that the driver has received an interrupt in linux?

问题 I have a PCIe device that will send a hardware interrupt when a data buffer is ready to be read. I believe the best approach for this is to use signals but I'm not entirely sure how. What I believe I need to do is: Save the PID of the user space application so the driver knows where to send the signal In the interrupt handler of the PCIe device driver, send a signal to the user space application In the User space application implement a signal handler function for processing the signal I'm

Writing files in the background process

阅读更多关于 Writing files in the background process

问题 I am trying to create a script that will process modified/new files in a directory (which is being mirrored from a remote directory by lftp but that's another story). To keep track of the files that are modified I use fswatch . I then convert the files detected by fswatch from xml to json and store them in a separate directory. To make sure that I can stop this conversion once there are no more files to process (when the mirroring job is over) I keep track of a file that will be created by

Identifying PID source of DNS request (Windows XP)

阅读更多关于 Identifying PID source of DNS request (Windows XP)

问题 I wish to identify the process that is making DNS requests. Looking at the query gives me a clue, but doesn't help me identify the exact process. I can see the local port number in Wireshark, but the request is too transient to be picked up by TCPView. Is there a logging tool which will catch DNS requests and PID? 回答1: Process Monitor from Sysinternals will give you what you want. Limit the capture to just network activity and you'll see the activity along with the PID and process name. The

Modify PID manager for multi-threading

阅读更多关于 Modify PID manager for multi-threading

问题 Below is my PID manager. I want to modify it so it uses multi-threading. Therefore I would like for each thread to request a pid (maybe create 20 or so like I do in the while loop), sleep for a random period of time (I assume use sleep() ), and then release the pid (similar to what you see below). I am a total newbie when it comes to threads in C and Linux so if someone can help me modify this accordingly. Would I start with the clone() function call? #include <stdio.h> #include <stdlib.h>

How to squeeze in additional parameters to a reaper function when a parent is signalled to kill a child (c)?

阅读更多关于 How to squeeze in additional parameters to a reaper function when a parent is signalled to kill a child (c)?

问题 I'm writing a TCP server that functions very much like a chatroom and came across this question. When a user connects, a child process is created to serve the user. When a user logs in, I store his username into a text file, online.txt But when a user logs out, I need to remove the user from online.txt (PROBLEM), the parent then signals a reaper() and kills the child. My questions are: Q1: How I can squeeze in additional information to the reaper (such as the username that the user used to

Is it possible to find out whether a process was started by a user or by another process via CreateProcess or ShellExecute?

阅读更多关于 Is it possible to find out whether a process was started by a user or by another process via CreateProcess or ShellExecute?

问题 I wanted to know if there was any way of checking if a particular process was started by the user by him/her double clicking, typing the required commands in cmd, via the address bar in explorer, etc. or by another program using CreateProcess() or ShellExecute(). I tried checking the parent process id of the created process but failed to see any consistency among the parent pids of the user initiated processes. I wanted to know if there was any other way or a fool proof way using the ppids.

Problem passing parameter to applescript via terminal/bashscript

问题 I'm trying to control multiple VLC instances via bashscript and applescript - i access them via their pid. I got this working in a small manual test, which works fine: tell application "System Events" set VLC_VGA to application processes whose unix id is 598 repeat with proc in VLC_VGA set the frontmost of proc to true keystroke "p" using {command down} end repeat end tell I now want to dynamically insert the pid (598 or whatever it may be). This is what I have so far - but won't work:

Sending message Pid Erlang

阅读更多关于 Sending message Pid Erlang

问题 I would like to know, how can i send a message to process with erlang. I did start a process and the output shows me that the pid is <0.39.0>. My problem is how can i send a message to this process (<0.39.0>) manually. Anyhelp would be appreciated 回答1: While list_to_pid/1 can indeed be used to construct a PID and use it to send messages its usage is discouraged: This BIF is intended for debugging and for use in the Erlang operating system. It should not be used in application programs. A
