Linux File Descriptor Sync at Ethan Carruthers blog

Linux File Descriptor Sync. I have the following code: Sync () causes all pending modifications to filesystem metadata and cached file data to be written to the underlying filesystems. The fsync() function shall request that all data for the open file descriptor named by fildes is to be transferred to the storage device associated with. In 2020, on linux versions 5.6 and above, a new system call was added to linux that’ll enable a process to obtain a duplicate of a file descriptor of. Given a pathname for a file, open () returns a file descriptor, a small, nonnegative integer for use in subsequent system calls (read (2), write. This file descriptor can be used as the dirfd argument in calls to fchownat(2), fstatat(2), linkat(2), and readlinkat(2) with an empty pathname to have. Int fdfile = open(testfile.txt, o_rdonly | o_sync); File *file = fopen(testfile.txt, r+);

Int fdfile = open(testfile.txt, o_rdonly | o_sync); This file descriptor can be used as the dirfd argument in calls to fchownat(2), fstatat(2), linkat(2), and readlinkat(2) with an empty pathname to have.
