Reading a whole folder| marlinde17 (16) |  |
| Hi, I am currently working on a program that reads numerical data from a file and analyzes it (searches for a maximum, etc.). Is there a way I can input the name of a whole folder and have the program open, analyze, and close all files in that folder? Any input is greatly appreciated. Thanks | |

| There are a lot of ways to do it. I suggest you start here: http://linux.die.net/man/3/opendir Be sure to look through the links at the bottom of the page. opendir() +readdir()/scandir() +closedir() are for reading the directory's contents something like you would read a normal file. glob() is to get a list of files that match a pattern (like "foo/*.c") getdirentries() is a common but non-POSIX function that returns a list of filenames. ftw() provides a nice abstraction over the fts_x() functions to call a function that you provide once for each directory entry. Hope this helps. | |
