问题

我尝试了这个：

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

但它无法编译通过：

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

我尝试查找类似的例子（例如sqlite），但它们似乎使用了相同的习惯用法，但可以编译通过。

英文:

I try this

name := C.CString(&quot;vds&quot;)
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

尝试显式转换它：

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

英文:

Try explicitly casting it:

name := C.CString(&quot;vds&quot;)
C.OpenService(scm, (*C.CHAR)(unsafe.Pointer(name)), C&gt;DWORD(C.SC_MANAGER_ALL_ACCESS))
