Struct linux_object::process::LinuxProcess

pub struct LinuxProcess { /* private fields */ }

Linux specific process information.

Implementations

impl LinuxProcess

pub fn lookup_inode_at(
    &self,
    dirfd: FileDesc,
    path: &str,
    follow: bool
) -> LxResult<Arc<dyn INode>>

Lookup INode from the process.

• If path is relative, then it is interpreted relative to the directory referred to by the file descriptor dirfd.

• If the dirfd is the special value AT_FDCWD, then the directory is current working directory of the process.

• If path is absolute, then dirfd is ignored.

• If follow is true, then dereference path if it is a symbolic link.

pub fn lookup_inode(&self, path: &str) -> LxResult<Arc<dyn INode>>

Lookup INode from the process.
