Enum FcntlArg

#[non_exhaustive]
pub enum FcntlArg<'a>

Commands for use with fcntl.

Variants

F_DUPFD(RawFd)

Duplicate the provided file descriptor

F_DUPFD_CLOEXEC(RawFd)

Duplicate the provided file descriptor and set the FD_CLOEXEC flag on it.

F_GETFD

Get the close-on-exec flag associated with the file descriptor

F_SETFD(FdFlag)

Set the close-on-exec flag associated with the file descriptor

F_GETFL

Get descriptor status flags

F_SETFL(OFlag)

Set descriptor status flags

F_SETLK(&'a flock)

Set or clear a file segment lock

F_SETLKW(&'a flock)

Like F_SETLK except that if a shared or exclusive lock is blocked by other locks, the process waits until the request can be satisfied.

F_GETLK(&'a mut flock)

Get the first lock that blocks the lock description

F_OFD_SETLK(&'a flock)

Acquire or release an open file description lock

F_OFD_SETLKW(&'a flock)

Like F_OFD_SETLK except that if a conflicting lock is held on the file, then wait for that lock to be released.

F_OFD_GETLK(&'a mut flock)

Determine whether it would be possible to create the given lock. If not, return details about one existing lock that would prevent it.

F_ADD_SEALS(SealFlag)

Add seals to the file

F_GET_SEALS

Get seals associated with the file

F_GETPIPE_SZ

Return the capacity of a pipe

F_SETPIPE_SZ(c_int)

Change the capacity of a pipe
