Re: [go-nuts] [CGO] How can I convert GoString to wchar_t?
wchar_t is a 16 bits value representing a UTF16 character so you could
convert Go strings to and from UTF16 using the unicode/utf16 package.

[go-nuts] [CGO] How can I convert GoString to wchar_t?
Hi gophers,
I'm trying to write the Golang wrapper for a dll with CGO.
A wrapper that will only work in windows.
I need to be able to send UTF-8 or unicode strings to c.
This issue was never asked on platforms like stackoverflow.
So I couldn't find a solution.

https://github.com/dkager/tolk/blob/master/src/Tolk.h#l100
line 100
I am adding the code I tried below:
package talker
//#cgo windows CFLAGS: -DGO_WINDOWS -Iinclude
//#cgo windows LDFLAGS: -Llib/x64 -lTolk
//#include "Tolk.h"
import "C"
// import "unsafe"
func Load() {
C.Tolk_Load()
}
func IsLoaded() bool {
if C.Tolk_IsLoaded() == false {
return false
}
return true
}
func Unload() {
C.Tolk_Unload()
}
// problem: the function I can't find a solution for.
func DetectScreenReader() string{
return C.GoString(C.Tolk_DetectScreenReader())
}
func HasBraille() bool{
b := C.Tolk_HasBraille()
if (b == false) {
return false }
return true
}
// problem: the second function I can't find a solution for ..
func Output(text string, interrupt bool) {
b := C.bool(bool)
C.Tolk_Output((*C.wchar_t)(text), b)
}
error: .\talker.go:39:28: cannot convert text (type string) to type
*_Ctype_ushort
