What did you do?
I wrote a Go function named Foo(), whith calls os.UserConfigDir() and prints out the result or error. Function Foo() is exported to shared library through CGO, then is called in c program.
~/issue $ ls -R
.:
foo.c test
./test:
go.mod test.go
~/issue $ cat foo.c
#include
#include
#include
#include
int main() {
// Call the Foo() function and print the result
char* result = Foo();
printf("Result: %s\n", result);
return 0;
}
~/issue $ cat test/test.go
package main
import (
"C"
"os"
)
func main() {
}
//export Foo
func Foo() *C.char{
dir, err := os.UserConfigDir()
if err != nil {
return C.CString(err.Error())
}
return C.CString(dir)
}
