type Options ¶

type Options struct {
	// Argv is the set of arguments to exec with.
	// `Argv[0]` is the name of the binary as invoked.
	// If Argv is empty, it will default to a single-element slice, with
	// `Argv[0]` being the binary name.
	Argv []string

	// Envv is the set of environment variables to pass to the executed process.
	Envv []string

	// Files is the set of file descriptors to pass to forked processes.
	// Only used when forking, not pure exec'ing.
	Files []uintptr
}
