func Test ¶

func Test(filePath string)

Test This tests shows that Golang is a 'komplete Scheiße'. What does that mean ? Here we are using system calls without any type casts. We use pointers returned by a DLL library directly, i.e. we use pointers returned by C code, and we do not type cast them into Go pointers except one thing. We are using the Go's `uintptr` type, because system calls use them, and we have no other choice other than this. Well, this very simple experiment shows that a pointer to Mix_Music type is not NULL according to the non-zero printed value. What happens next ? This pointer is given to another DLL function. In C code this function returns a positive value of 503, but in Golang it returns zero (0). What does it mean ? Golang is a 'komplete Scheiße'. I and will not create an issue on Golang's GitHub page because they will say as they usually do that they are great and we are nothing. This small example shows how "great" is Golang in reality. Golang ist komplete Scheiße. Das stimmt.
