用cgo将字符串传递给win32函数

Question

I try this

name := C.CString("vds")
C.OpenService(scm, (name), C.DWORD(C.SC_MANAGER_ALL_ACCESS))

but it wont compile

.\test.go:28: cannot use name (type *C.char) as type *C.CHAR in argument to _Cfunc_OpenService

I tried looking for similar things (sqlite for example) but they seem to use this same idiom, but it compiles

Answer 1

Try explicitly casting it:

name := C.CString("vds")
C.OpenService(scm, (*C.CHAR)(unsafe.Pointer(name)), C>DWORD(C.SC_MANAGER_ALL_ACCESS))
