permissions

问题 I managed to get my hands on a nifty ftp object. It is very low level and easy to adapt. I'm using it to transfer files from one Mac to another via FTP. Now, the issue I'm having is that when the file, that is transfered, reaches its destination, the other Mac, the access permissions is set , at random intervals, to "Everyone" : "No Access". So sometimes, whatever I do with the files fails randomly because my application can't access the files. Is there a way I can change the file's access

I'm sure I'm doing a noob error with the permissions between the user and the web server, but I don't see what error. I see that didongo

问题 What's the simplest way to copy the unix file permissions of a file and set them to another file? Is there a way to store a file's permissions to a variable and then use that variable to set those permissions to another file? 回答1: Sure. Use stat() and chmod() (may need root). #include <sys/stat.h> struct stat st; stat("/foo/bar.txt", &st); chmod("/baz/quirk.jpg", st.st_mode); 来源： https://stackoverflow.com/questions/16680302/c-copy-file-permissions-from-another-file
