问题 How can I change my current working directory in C++ in a platform-agnostic way? I found the direct.h header file, which is Windows compatible, and the unistd.h , which is UNIX/POSIX compatible. 回答1: The chdir function works on both POSIX (manpage) and Windows (called _chdir there but an alias chdir exists). Both implementations return zero on success and -1 on error. As you can see in the manpage, more distinguished errno values are possible in the POSIX variant, but that shouldn't really

Get current batchfile directory

问题 Firstly, I saw this topic but I couldn\'t understand that. Question : There is a batch file in D:\\path\\to\\file.bat with following content : echo %cd% pause Output is : C:\\ It must be D:\\path\\to What am I doing wrong? 回答1: System read-only variable %CD% keeps the path of the caller of the batch, not the batch file location. You can get the name of the batch script itself as typed by the user with %0 (e.g. scripts\mybatch.bat ). Parameter extensions can be applied to this so %~dp0 will

I'm making a C program where I need to get the directory that the program is started from. This program is written for UNIX computers. I've been looking at opendir() and telldir() , but telldir() returns a off_t (long int) , so it really doesn't help me. How can I get the current path in a string (char array)? Mic Have you had a look at getcwd() ? #include <unistd.h> char *getcwd(char *buf, size_t size); Simple example: #include <unistd.h> #include <stdio.h> #include <limits.h> int main() { char cwd[PATH_MAX]; if (getcwd(cwd, sizeof(cwd)) != NULL) { printf("Current working dir: %s\n", cwd); }

Hard-Coding is not an option- it needs to be adaptable if it\'s moved to another location. I want to dump a bunch of CSV files in a folder, have the program recognize all the files, then load the data and manipulate them. I really just want to know how to navigate to that folder. 回答1: One way would be to use the system property System.getProperty(

问题 Is there a platform-agnostic and filesystem-agnostic method to obtain the full path of the directory from where a program is running using C/C++? Not to be confused with the current working directory. (Please don\'t suggest libraries unless they\'re standard ones like clib or STL.) (If there\'s no platform/filesystem-agnostic method, suggestions that work in Windows and Linux for specific filesystems are welcome too.) 回答1: Here's code to get the full path to the executing app: Windows: int
