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

RETURN VALUE         top

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

       Returned errors may indicate the following problems:

           Specified parameter is invalid.

           Message has been sealed.

           Message is in invalid state.

           Message cannot be appended to.

           Memory allocation failed.

NOTES         top

       These APIs are implemented as a shared library, which can be compiled
       and linked to with the libsystemd pkg-config(1) file.
