NAME

       sd_bus_message_append_strv - Attach an array of strings to a message

SYNOPSIS

       #include <systemd/sd-bus.h>

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

DESCRIPTION

       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

       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

       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.
