func main() {
    var (
        str    = "a=aaa,b=bbb,c=ccc"
        format = "a=%s,b=%s,c=%s"

        a string
        b string
        c string
    )

    if _, err := fmt.Sscanf(str, format, &a, &b, &c); err != nil {
        log.Fatal(err)
    }

    log.Println("a:", a)
    log.Println("b:", b)
    log.Println("c:", c)
}

output: 2022/09/21 17:18:41 unexpected EOF

// Sscanf scans the argument string, storing successive space-separated // values into successive arguments as determined by the format. It // returns the number of items successfully parsed. // Newlines in the input must match newlines in the format.

func Sscanf(str string, format string, a ...any) (n int, err error) {

return Fscanf((*stringReader)(&str), format, a...)
