Hi,
I have already gone through this doc.
The thing is I am getting two different pseudo versions for two different
go versions.
Are you saying I should get pseudo version v0.0.0 for both the go versions?

I understand by running the service as containers is one route through

My query is if I want to avoid that route , is there a way to achieve this

These are normal, ordinary, problems when writing C cod

Hi,
I want to convert *C.char to array of strings in Go.
I want to do this because I want the first word from the string.Strings are
getting appended to *C.char and I want the first word of the string.
I am doing it using 'strings.Split(C.GoString(*C.char))[0]', but it is
giving error.

Hi Tamás,
If I return LogMessage type of object from C code, what type of object
should be there on Go side to receive the return value because the Go side
doesn't have a LogMessage object ?
Thanks

Hi Jan,
Can I pass a pointer to a value from Go to C, do some manipulation on it
within the C code and access the value from Go after the C code executes ?
Thanks

Hi,
I want to call C code from GO code.Once the C code gets executed I want to
pass the value back to the GO code.
Can someone please guide me as in how to pass value back from C code to the
GO code.
Thanks
