SD_BUS_M...END_STRV(3) sd_bus_message_append_strv SD_BUS_M...END_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_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.
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.
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.
