create a pointer to a channel in go

To create a pointer to a channel in Go, you simply declare a channel using the make function and then take its address using the & operator. Here's an example:

main.go
package main

import "fmt"

func main() {
    ch := make(chan int)
    ptrCh := &ch
    fmt.Printf("Type of ch: %T\n", ch)
    fmt.Printf("Type of ptrCh: %T\n", ptrCh)
}

11 lines

In this example, we first create a channel ch using the make function. Then, we take its address with & and assign it to ptrCh, which is a pointer to the channel.

Finally, we print the types of both ch and ptrCh. The output will be:

main.go
Type of ch: chan int
Type of ptrCh: *chan int
46 chars
3 lines

Note the * before chan int in the type of ptrCh, indicating that it is a pointer to a channel.
