NAME         top

       sd_bus_message_read_strv - Access an array of strings in a message

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 strings in
       message m. The "read pointer" in the message must be right before an
       array of strings. On success, a pointer to the 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 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.
