Enum file_descriptors::InvalidPathReason

pub enum InvalidPathReason {
    TooManySymbolicLinks,
    TooLong,
    IsADirectory,
    DoesNotExist,
    ParentComponentIsNotADirectory,
    ExistsButCanNotBeUsed,
}

Reason given for why a path is an invalid for a FIFO.

Variants

TooManySymbolicLinks

Equivalent to ELOOP.

TooLong

Equivalent to ENAMETOOLONG.

IsADirectory

Equivalent to EISDIR.

DoesNotExist

Does not exist.

A component of the FIFO path does not exist.

ParentComponentIsNotADirectory

One of the parent components of the path (ie not the file name) is not a directory.

ExistsButCanNotBeUsed

The path points to something that exists but:-

• it is not a device special file (character or block device) backed by a device, or;
• it is on a read-only file system and writes need to occur (this should not normally occur), or;
• it is an executable image currently being executed and writes need to occur.
