пропускать элементы в автобусном сообщении (Skip elements in a bus message)
Имя (Name)
sd_bus_message_skip - Skip elements in a bus message
Синопсис (Synopsis)
#include <systemd/sd-bus.h>
int sd_bus_message_skip(sd_bus_message *
m, const char*
types);
Описание (Description)
sd_bus_message_skip()
is somewhat similar to
sd_bus_message_read(3), but instead of reading the contents of
the message, it only moves the "read pointer". Subsequent read
operations will read the elements that are after the elements
that were skipped.
The types argument has the same meaning as in
sd_bus_message_read()
. It may also be NULL
, to skip a single
element of any type.
Возвращаемое значение (Return value)
On success, sd_bus_message_skip()
returns 0 or a positive
integer. On failure, it returns a negative errno-style error
code.
Errors
Returned errors may indicate the following problems:
-EINVAL
The m parameter is NULL
.
-EBADMSG
The message cannot be parsed.
-EPERM
The message is not sealed.
-ENXIO
The message end has been reached and the requested elements
cannot be read.
-ENOMEM
Memory allocation failed.
