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.
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.
sd_bus_message_skip() was added in version 240.
