I want to run the main goroutine on another thread besides the main thread,
so that the main thread can block in darwin UI code. Is this a safe way to
do it?
package main
/*
#include <pthread.h>
#include <stdio.h>
void block() {
printf("Blocking main thread? %d\n", pthread_main_np());
while(1);
}
*/
import "C"
import (
"fmt"
"runtime"
)
func init() {
runtime.LockOSThread()
go main()
C.block()
}
func main() {
fmt.Println("Blocking main goroutine?", C.pthread_main_np())
}
This prints out the following:
$ go run threadtrick.go
Blocking main thread? 1
Blocking main goroutine? 0
