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