Yes, you are doing the right thing :) However, the issue is that no
other interface (other than systemd) has been added to Elput yet. If you
would like to create a non-systemd interface for it, we would be happy
to review that code for inclusion in upstream git.
The functions needed to implement a new Elput_Interface are pretty simple:
typedef struct _Elput_Interface
{
Eina_Bool (*connect)(Elput_Manager **manager, const char *seat,
unsigned int tty);
void (*disconnect)(Elput_Manager *manager);
int (*open)(Elput_Manager *manager, const char *path, int flags);
void (*open_async)(Elput_Manager *manager, const char *path, int flags);
void (*close)(Elput_Manager *manager, int fd);
Eina_Bool (*vt_set)(Elput_Manager *manager, int vt);
} Elput_Interface;
The only ones above that you would Need to implement would be: connect,
disconnect, open, close ... all others are optional.
Kind Regards,
