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.

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.
