Compile for non OpenBSD systems 
Previously the compilation would fail for non OpenBSD systems & the
user had to manage it themselves. Now it compiles on non OpenBSD
systems but returns nil immediately because unveil isn't supported on
those systems.

Examples

UnveilCommands

UnveilCommands takes a slice of commands & unveils them one by one, it will return an error if unveil fails at any step. "no such file or directory" error is ignored because binaries are not placed in every PATH.

Default permission is "rx".

package main

import "tildegit.org/andinus/lynx"

func main() {
	commands := []string{"cd", "ls", "rm"}

	err = lynx.UnveilCommands(commands)
	if err != nil {
		log.Fatal(err)
	}
}

UnveilPaths / UnveilPathsStrict

UnveilPaths takes a map of path, permission & unveils them one by one, it will return an error if unveil fails at any step. "no such file or directory" error is ignored, if you want to get that error too then use UnveilPathsStrict.

package main

import "tildegit.org/andinus/lynx"

func main() {
	paths := make(map[string]string)

	paths["/home"] = "r"
	paths["/dev/null"] = "rw"
	paths["/etc/examples"] = "rwc"
	paths["/root"] = "rwcx"

	err = lynx.UnveilPaths(paths)
	if err != nil {
		log.Fatal(err)
	}

	// This will return an error if the path doesn't exist.
	err = lynx.UnveilPathsStrict(paths)
	if err != nil {
		log.Fatal(err)
	}
}
