Hi Jusitn,
I realised I have value_len field in my arguments.I did this :
func Nitish(key *C.char, value *C.char, value_len C.size_t){
f.WriteString(C.GoString(key)+ ":")
s := C.GoStringN(value, C.int(value_len))
//fmt.Println(s)
f.WriteString(s)
f.WriteString("\n")
}
Am I doing it correctly?
Hi Justin,
As you had suggested:
You could use something like this:
https://play.golang.org/p/fcE2UJEUFPy
That example has the option of only converting a fixed number of bytes from
the C string to the Go string, if you know how big the prefix is.

Actually, this is what is happening:
func Nitish(key *C.char, value *C.char, value_len C.size_t){
f.WriteString(C.GoString(key)+ ":")
f.WriteString(C.GoString(value))
f.WriteString("\n")
}
This callback method is getting called from C code multiple times.

Hi,
I have this method:
func CallBack(key *C.char, value *C.char, value_len C.size_t){
}
and the *value* parameter in the arguments is containing the given string
'Fp5PpR2roT6uPnte47 image/gif'.
I want to extract only first word from the string.Let me know how can I do
this.
I don't wa

Are you literally doing this?
strings.Split(C.GoString(*C.char),"")
Something like this should be wor
Apologies.I did this 'strings.Split(C.GoString(*C.char),"").
I am getting 'Incompatible types' compilation error.
Thanks
