I have to pass a string to a C file from a bmax one.

On the file there is:
char s[80];
void func(?)
{
...
}
and on the bmax file i need to write:
import "file.c"
extern
function func(?)
end extern

func("string")

What should i write on the places i've marked with a "?" ?

void func ( char *cString )

and

function func ( chars:byte ptr )

and then call it by:

func ( "string".tocstring () )

- Should work,

But after called the func function i have to do:

char s[80];

func(string)
s=string

and with this method isn't possible(i work char, not char *).

You could use strcpy, ie:

strcpy ( &s, cString );

I think you would need to change the function decleration to:

func ( const char *cString )
