Implementations§

Source§

impl<'a> SpawnAction<'a>

Source

pub const USE_FOR_STDIO: i32 = 32_768i32

Source

pub fn clone_fd(local_fd: BorrowedFd<'a>, target_fd: i32) -> Self

Clone a file descriptor into the new process.

local_fd: File descriptor within the current process. target_fd: File descriptor within the new process that will receive the clone.

Source

pub fn transfer_fd(local_fd: OwnedFd, target_fd: i32) -> Self

Transfer a file descriptor into the new process.

local_fd: File descriptor within the current process. target_fd: File descriptor within the new process that will receive the transfer.

Source

pub fn add_namespace_entry(prefix: &'a CStr, handle: Handle) -> Self

Add the given entry to the namespace of the spawned process.

If SpawnOptions::CLONE_NAMESPACE is set, the namespace entry is added to the cloned namespace from the calling process.

Source

pub fn add_handle(kind: HandleInfo, handle: Handle) -> Self

Add the given handle to the process arguments of the spawned process.

Source

pub fn set_name(name: &'a CStr) -> Self

Sets the name of the spawned process to the given name.
