Nitish privately e-mailed me:
Can you please specify the particular files in YottaDB repository that are
exchanging key-value pairs between C and Go ?
I am replying to the threadd.
Look at the buffer_t* and key_t* files. You can also trace the
implementations of NodeNextE(), SubNextE(),
Nitish –
As noted, you cannot pass to C a pointer to Go structure. However, Go can
use pointers C structures that are provided to it. YottaDB passes key-value
tuples between C and Go, and you can look at working code that does this at

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

You do it exactly as though you passed a pointer to a Go function, and
then accessed the value after the Go
Thanks for the info. Jan.My main issue is how can I access the value on Go
side after some manipulation within the C code ?
Thanks

The first part of the question is discussed in great detail here:
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

What C type the value is?
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
