Hello Folks,
Having some confusion for freeing memory allocated by C.String().
Filter_CSo my program is something like below.
A. Should we just call C.Free after line 6 for Filter_C directly or defer
is just fine.
B. Currently we are expecting the user of fetchdata() to free the
Context_C, any alternates ?
test_go.go
=========
1 func fetchdata(x int, Filter String) (int32,String) {
2 var Context_C *C.char
3 Filter_C = C.String(Filter)
4 defer C.free(unsafe.Pointer(Filter_C))
5
6 Context_C = C.Getdata(Filter_C) <<===== Context_C
receives string from a malloc buffer
7
8 return 1,C.GoString(Context_C)
9
10 }
Thanks
