NAME         top

       sd_bus_message_read_strv - Access an array of strings in a

SYNOPSIS         top

       #include <systemd/sd-bus.h>

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

DESCRIPTION         top

       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.

RETURN VALUE         top

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

       Returned errors may indicate the following problems:

           m or l are NULL.

           The message is not sealed.

           The message cannot be parsed.

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