NAME

       sd_bus_message_read_strv - Access an array of strings in a message

SYNOPSIS

       #include <systemd/sd-bus.h>

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

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.

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.
