We call them from the Xapian C++ library by adding 'extern "C"' wrappers
to the *header* files like so:
#ifdef __cplusplus
extern "C" {
#endif
/* This file was generated automatically by the Snowball to ANSI C
* compiler */
extern struct SN_env * snowball_english_create_env(void);
extern void snowball_english_close_env(struct SN_env * z);
extern int snowball_english_stem(struct SN_env * z);
#ifdef __cplusplus
}
#endif
Then just include this from your C++ source and call the functions as
you would from C. It would be good if the snowball compiler added this
wrapper. Martin: the changes should be obvious, but let me know if you
want a patch.
Cheers,
