The plugin module (pluginex1.go):
[java]
package main
import “fmt”
func Talk() {
fmt.Println(“Hello From Plugin !”)
}
[/java]
Build the plugin module:
[java]
# go build -buildmode=plugin -o pluginex1.so pluginex1.go
[/java]
Invoke the plugin module (pluginex1main.go):
[java]
package main
import(
“os”
“fmt”
“plugin”
)
func main() {
plugin, err := plugin.Open(“pluginex1.so”)
if err != nil {
fmt.Println(err)
os.Exit(-1)
}
sym, err := plugin.Lookup(“Talk”) // reflection
if err != nil {
fmt.Println(err)
os.Exit(-1)
}
sym.(func())()
}
[/java]
. . .
