systemd sd_bus_message_append_strv 3 sd_bus_message_append_strv Attach an array of strings to a message #include <systemd/sd-bus.h> int sd_bus_message_append_strv sd_bus_message *m char **l 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_basic3. 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. On success, this call returns 0 or a positive integer. On failure, a negative errno-style error code is returned. systemd1 sd-bus3 sd_bus_message_append3 sd_bus_message_append_array3 The D-Bus specification
