Functions

bind_to_fd

Bind a handle to a specific file descriptor.

clone_channel

Clones an object’s underlying handle and checks that it is a channel.

clone_fd

Clones an object’s underlying handle.

create_fd

Create an object from a handle.

create_transferrable

Creates a transferrable object and returns one end as a zx::Channel.

get_vmo_copy_from_file

Gets a read-only VMO containing the whole contents of the file. This function creates a clone of the underlying VMO when possible, falling back to eagerly reading the contents into a freshly-created VMO.

get_vmo_exact_from_file

Get a read-only handle to the exact VMO used by the file system server to represent the file. This VMO will track size and content changes to the file.

get_vmo_exec_from_file

Gets a read-exec VMO containing the whole contents of the file.

open

Opens the remote object at the given path with the given flags asynchronously. (‘asynchronous’ here is referring to fuchsia.io.Directory.Open not having a return value).

open_at

Opens the remote object at the given path relative to the given dir with the given flags asynchronously. (‘asynchronous’ here is referring to fuchsia.io.Directory.Open not having a return value).

open_fd

Opens the remote object at the given path with the given flags synchronously, and on success, binds that channel to a file descriptor and returns it.

open_fd_at

Opens the remote object at the given path relative to the given dir with the given flags synchronously, and on success, binds that channel to a file descriptor and returns it.

pipe_half

Creates a named pipe and returns one end as a zx::Socket.

service_connect

Connects a channel to a named service.

service_connect_at

Connects a channel to a named service relative to a directory dir. dir must be a directory protocol channel.

spawn

Spawn a process in the given job.

spawn_etc

Spawn a process in the given job using a series of SpawnActions. All SpawnActions are nullified after their use in this function.

spawn_vmo

Spawn a process in the given job using an executable VMO.

transfer_fd

Removes an object from the file descriptor table and returns its underlying handle.
