[go-nuts] Re: [cgo ] Export go function to C - illegal character
hi
don't success to solve this subject. Here an example with the simple code
shown in those slides:
http://akrennmair.github.io/golang-cgo-slides/#10
This code doesn't works anymore, or perhaps there is some special command
line to build it ?
I thought it was possible to create a C function wich export the mangle
name wich call the go code. When i put my c code in a c file in the
directory, the c file is not compiled.

[go-nuts] Re: [cgo ] Export go function to C - illegal character
as asked by Jason, i give more information.
I build a 32 bits .dll and there was no error message. When i launch the
dll with the c program, the c program return a generic error message
"method is not recognized" wich happens when the entry point name is wrong.
So the C program expected a function named _RVExtension@12 and go returns
#ifdef __cplusplus
extern "C" {
#endif
extern void _RVExtensionVersion(char* p0, size_t p1);
extern void _RVExtensionArgs(char* p0, size_t p1, char* p2, char** p3, int
p4);
extern void _RVExtension(char* p0, size_t p1, char* p2);
#ifdef __cplusplus
}
#endif

Hello,
I need some assistance to export a GO dll function to a C program.
The C program (wich i m not the author) required to call a function
with this name: _RVExtension@12
so, i simply declare my go function like this:
//export _RVExtension@12
func _RVExtension@12(output *C.char, outputsize C.size_t, input *C.char
) {Saisissez le code ici...
but when i try to compile it, it returns an illegal character U+0040
'@' error.
Do you know if there is a workaround about this ? I m not familiar with
C code and i don't understand why there is @12 in the function name.
note: for the 64 bits the entry point is simple : RVExtension and it
works perfectly well.

[go-nuts] Re: [cgo ] Export go function to C - illegal character
The @12 part isn't legal as part of a function name, as the compiler is
telling you. You must remove it.
