Yes. Such additional information is really useful to debug brlapi
issues.

brlapi_error_t * brlapi_error_location(void);
const char * brlapi_strerror(const brlapi_error_t *error);

So brlapi_strerror(brlapi_error_location()) will return what you want,
i.e. the string that brlapi_error() would have printed.

Cc-ing me would have been useful, "braille" just happened to catch my
eye by luck while looking over qemu mails :)
