syncfs

Implemented in Antinomie 0.7.0 · Syscall list

long syncfs(int fd);
Number (x86-64) 306
ABI common
Kernel entry point sys_syncfs

This is the raw kernel prototype from the pinned Linux 6.12.94 schema, not the libc wrapper.

Flushes the whole filesystem that contains a file descriptor.

Name Type Meaning
fd (arg0) int File descriptor to operate on.

On success: 0.

In an Antinomie trace the Return column and the ret filter field show the raw kernel return value. On failure that is the negative errno, for example -2 for ENOENT, not the -1 plus errno that the libc wrapper gives. syscall.errno holds the positive errno and syscall.success is false.

Raw return Name Meaning
-9 EBADF A file descriptor is not valid for this operation.
-5 EIO An input/output error occurred.

syncfs(2) on man7.org

Coverage mark: Implemented. All arguments are plain values, recorded as the raw argument words at entry. There is no pointee to copy and no known gap.

Every call is recorded as an Entry record (the six argument words and the pointees copied at entry) and an Exit record (the return value and the pointees copied at exit).

Argument When How Recorded field key Condition
fd (arg0) Entry raw scalar word args.0, args.fd
  • Result: ret, syscall.errno, syscall.success, syscall.duration_ns.
  • Argument words: args.fd (arg0); args.0 to args.5 by position.

See Syscall Trace filter for the full syntax.
