Имя (Name)

sd_bus_message_read_strv - Access an array of strings in a
       message

---

Синопсис (Synopsis)

#include <systemd/sd-bus.h>

       int sd_bus_message_read_strv(sd_bus_message *m, char ***l);

---

Описание (Description)

sd_bus_message_read_strv() gives access to an array of
       string-like items in message m. The "read pointer" in the message
       must be right before an array of strings (D-Bus type "as"),
       object paths (D-Bus type "ao"), or signatures (D-Bus type "ag").
       On success, a pointer to a NULL-terminated array of strings is
       returned in the output parameter l. Note that ownership of this
       array is transferred to the caller. Hence, the caller is
       responsible for freeing this array and its contents.

Возвращаемое значение (Return value)

On success, sd_bus_message_read_strv() returns a non-negative
       integer. On failure, it returns a negative errno-style error
       code.

   Errors
       Returned errors may indicate the following problems:

       -EINVAL
           m or l are NULL.

       -EPERM
           The message is not sealed.

       -EBADMSG
           The message cannot be parsed.

       -ENXIO
           The message "read pointer" is not right before an array of
           the appropriate type.
