SD_BUS_MESSAGE_SKIP(3) sd_bus_message_skip SD_BUS_MESSAGE_SKIP(3)
sd_bus_message_skip - Skip elements in a bus message
#include <systemd/sd-bus.h>
int sd_bus_message_skip(sd_bus_message *m, const char* types);
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.
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.
These APIs are implemented as a shared library, which can be compiled
and linked to with the libsystemd pkg-config(1) file.
