Thanks and Sorry for not providing more details. I'm on 1.9. No unsafe
package is used. Main program is a c program which calls into go functions
where some analytics are performed.
All calls to the golang use only strings and ints/floats/char. No structs
are passed. In Go all strings are conv
Some other errors that I've gotten from the the same program.

This program runs for about an hour and consumes about 1Gig of memory. I
was getting a lot of these errors, but they were significantly reduced when
I reduced the golang memory usage. (by reducing the in memory state that I
was keeping)
Any idea on how I can go about debugging this?

/src//folder1
/src//folder2

Everything works fine with go build ./src//...
I've recently added a module (/src//folder4) which calls go
code from c and and this go folder is built with:
go build --buildmode=c-archive -o libgolang.a
I'm not sure what the best practices are her

Any idea what (very rough is fine) that overhead is when compared to the
standard go toolchain?

Thanks for putting this together. I was trying to figure out how to do
callback from c to go. There are fewer examples on the web for that since
most of them deal with calling c code from go.
C int -> go C.int
C unsigned char -> C.uchar
C char -> C.char
C unsigned int -> C.uint
C double -> C.do
Thanks for reading my question. I'm trying to map c to Go "C."
C int -> go C.int
C unsigned char -> ?
C char -> ?
C unsigned short -> ?
C double -> ?
C __int64 -> ?
C *char -> C.string

I have a basic example working of calling back into go from C. If I have a
C function as:
func Add(a, b C.Int) C.Int {
return a + b
}
Where is the mapping of C type to C. when I want to pass additional
types to Go :
1. Unsigned int
2. char
3. double
4. string
5. short
etc...

I'm trying to port over some code using linear regression (statsmodule
package) in python to golang. I need the library to give me r square and p
values for each coefficient/variable.
Is there such a library in golang or c (that I can write bindings for)?
