NAME         top

       sd_bus_message_append_strv - Attach an array of strings to a
       message

SYNOPSIS         top

       #include <systemd/sd-bus.h>

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

DESCRIPTION         top

       The sd_bus_message_append() function can be used to append an
       array of strings to message m. The parameter l shall point to a
       NULL-terminated array of pointers to NUL-terminated strings. Each
       string must satisfy the same constraints as described for the "s"
       type in sd_bus_message_append_basic(3).

       The memory pointed at by p and the contents of the strings
       themselves are copied into the memory area containing the message
       and may be changed after this call. Note that the signature of l
       parameter is to be treated as const char *const *, and the
       contents will not be modified.

RETURN VALUE         top

       On success, this call returns 0 or a positive integer. On
       failure, a negative errno-style error code is returned.

   Errors
       Returned errors may indicate the following problems:

       -EINVAL
           Specified parameter is invalid.

       -EPERM
           Message has been sealed.

       -ESTALE
           Message is in invalid state.

       -ENXIO
           Message cannot be appended to.

       -ENOMEM
           Memory allocation failed.

NOTES         top

       Functions described here are available as a shared library, which
       can be compiled against and linked to with the
       libsystemd pkg-config(1) file.

       The code described here uses getenv(3), which is declared to be
       not multi-thread-safe. This means that the code calling the
       functions described here must not call setenv(3) from a parallel
       thread. It is recommended to only do calls to setenv() from an
       early phase of the program when no other threads have been
       started.
