-/**
- * Parse a trigger specification string.
- *
- * @param sdi The device instance for which the trigger specification is
- *            intended. Must not be NULL. Also, sdi->driver and
- *            sdi->driver->info_get must not be NULL.
- * @param triggerstring The string containing the trigger specification for
- *        one or more channels of this device. Entries for multiple channels are
- *        comma-separated. Triggers are specified in the form key=value,
- *        where the key is a channel number (or channel name) and the value is
- *        the requested trigger type. Valid trigger types currently
- *        include 'r' (rising edge), 'f' (falling edge), 'c' (any pin value
- *        change), '0' (low value), or '1' (high value).
- *        Example: "1=r,sck=f,miso=0,7=c"
- *
- * @return Pointer to a list of trigger types (strings), or NULL upon errors.
- *         The pointer list (if non-NULL) has as many entries as the
- *         respective device has channels (all physically available channels,
- *         not just enabled ones). Entries of the list which don't have
- *         a trigger value set in 'triggerstring' are NULL, the other entries
- *         contain the respective trigger type which is requested for the
- *         respective channel (e.g. "r", "c", and so on).
- *
- * @since 0.2.0
