关于在QT内调用Go函数问题,在mac上面一切正常，但是在windows下面传值就有问题了.
哈哈 虽然我也不知道
大神们，来个解答啊 …
package main
import (
"fmt"
"time"
)
type field struct {
name string
}
func (p *field) print() {
fmt.Printf("%p %s\n", p, p.name)
}
func TestClosure() {
// data := []*field{{"one"}, {"two"}, {"three"}}
one := new(field)
one.name = "one"
two := new(field)
two.name = "two"
three := new(field)
three.name = "three"
data := []*field{one, two, three}
for _, v := range data {
go v.print()
}
time.Sleep(3 * time.Second)
}
func TestClosure1() {
// data := []field{{"one"}, {"two"}, {"three"}}
var one field
one.name = "one"
var two field
two.name = "two"
var three field
three.name = "three"
data := []field{one, two, three}
for _, v := range data {
go v.print()
}
time.Sleep(3 * time.Second)
}
func TestClosure2() {
// data := []*field{{"one"}, {"two"}, {"three"}}
one := new(field)
one.name = "one"
two := new(field)
two.name = "two"
three := new(field)
three.name = "three"
data := []*field{one, two, three}
// for _, v := range data {
// go func() {
// v.print()
// }()
// }
for _, v := range data {
go func(x *field) {
x.print()
}(v)
}
time.Sleep(3 * time.Second)
}
func main() {
TestClosure()
fmt.Println("----")
TestClosure1()
fmt.Println("----")
TestClosure2()
}
defer 是在 return 之后执行的 …
package main
import (
"io"
"log"
)
func func1(s string) (n int, err error) {
defer func() {
log.Printf("func1(%q) = %d, %v", s, n, err)
}()
n = 7
err = io.EOF
return
}
func main() {
func1("Go")
}
src/ 下 …
// 不可以直接 src/main.go
ProjectName/main.go
// 直接把 vendor 放这里就行
vendor/ …
等正式版吧，测试版还不稳定 (nljb.net)
gdb
谢谢，谢谢
