sd_bus_message_append_strv - Attach an array of strings to a
message
Синопсис (Synopsis)
#include <systemd/sd-bus.h>
int sd_bus_message_append_strv(sd_bus_message *m, char **l);
Описание (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.
Возвращаемое значение (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.
Примечание (Note)
These APIs are implemented as a shared library, which can be
