sd_bus_message_append_strv - Attach an array of strings to a message
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.
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.
These APIs are implemented as a shared library, which can be compiled and linked
to with the libsystemd pkg-config(1) file.
