I thought you might Im writing many wrapper functions to C functions that
take multiple C.char*. All of these require a defer statement to free the C
string when the wrapper function terminates. Im absolutely sure Im going to
miss one or more of these out, so I was wondering if I could get hold of
the defer list, then I could encapsulate the construction with the defer in
a function.
e.g. roughly :
func NewCString(s string, deferList List) *C.char {
cs := C.CString(s)
deferList.PushBack(func() { C.free(cs) }
return cs
}
Then in an imagined world I could write my wrapper as :
func wrapper(s1 string, s2 string, s3 string) {
deferList := runtime.DeferList()
return C.inner(NewCString(s1,deferList)
}
