Struct command_fds::FdMapping

source · [−]

pub struct FdMapping {
    pub parent_fd: RawFd,
    pub child_fd: RawFd,
}

Expand description

A mapping from a file descriptor in the parent to a file descriptor in the child, to be applied when spawning a child process.

The parent_fd must be kept open until after the child is spawned.

Fields

parent_fd: RawFdchild_fd: RawFd
