mkdir

问题 After reading the mkdir(2) man page for the Unix system call with that name, it appears that the call doesn't create intermediate directories in a path, only the last directory in the path. Is there any way (or other function) to create all the directories in the path without resorting to manually parsing my directory string and individually creating each directory ? 回答1: There is not a system call to do it for you, unfortunately. I'm guessing that's because there isn't a way to have really

问题 I have a small script that create a directory for a user who registers an account on my site. This director is used to store images in that they upload. When I use mkdir() with permissions of 0777, the directory is created under the users name, but the permissions stay as 0755. I have tried a few different ways to do this, as follows; $path = path/to/directory/and/filename $old = umask(0); mkdir($path,0777); umask($old); also; $path = path/to/directory/and/filename/ mkdir($path, 0777, true);

问题 I made a function that tries to create a directory, and then write a simple file: buffer = "Hello world!"; string url = "a/b/c/d/"; string tmp = ""; string done = ""; while((tmp = GetBaseDir(url)).compare("")!=0){ done+=tmp; mkdir(done.c_str(), 0777); } // GetBaseDir returns "a/", and changes url to "b/c/d/" ofstream file; file.open((url+"file.txt").c_str(),ios::trunc); file << buffer; file.close(); As you can see, it only tries, if there is a failure it just keeps going on. I read that 'open

问题 I am trying to create a directory inside target based on a rule but for some reason the variable is not getting expanded i.e., $(OUT_DIR) is blank and mkdir -p does not work. Here is the code target_%: /home/user/%/.file : file.c export OUT_DIR = /home/user/$* ; \ mkdir -p $(OUT_DIR) ;\ . . . After making the changes suggested by @Beta, here is how the code looks like target_%: /home/user/%/.file : file.c export OUT_DIR=/home/user/$* ; \ mkdir -p $${OUT_DIR} ;\ cd $${OUT_DIR} ; \ ln -s /home

问题 I have a C++ program that takes user input for fopen in order to initiate a file write. Could someone help me find a function which will return a FILE* and use the Windows specific version of mkdir in order to create the folder structure for fopen to never fail to open a new file in the specified location because one of the folders does not exist. Thanks a bunch! 回答1: there's a method MakeSureDirectoryPathExists in the windows API, declared in dbghelp.h. It recursively creates directories, so

问题 We have some old applications that communicate via directory-based queues. Each item in the queue is a file, and there's a header file that maintains an ordered list of the filenames for the items in the queue. Naturally, this old code needs to lock the queue while items are pushed and popped. What it's doing is creating a lock subdirectory, on the assumption that mkdir() is an atomic operation - if multiple processes attempt to create a directory, only one of them is going to succeed. One of

问题 In docker, I want to copy a file README.md from an existing directory /opt/ibm/labfiles to a new one /input/tmp .
