SD\_BUS\_MESSAGE\_SKIP(3) sd\_bus\_message\_skip SD\_BUS\_MESSAGE\_SKIP(3)

.SH "NAME" sd\_bus\_message\_skip - Skip elements in a bus message

.SH "SYNOPSIS"

```
#include <systemd/sd-bus.h>
```

.HP 576u **int sd\_bus\_message\_skip(sd\_bus\_message \*m, const char* types);**

.SH "DESCRIPTION"

.PP **sd\_bus\_message\_skip()** is somewhat similar to [**sd\_bus\_message\_read**(3)](/man/os/systemd/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.

.PP 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.

.SH "RETURN VALUE"

.PP On success, **sd\_bus\_message\_skip()** returns 0 or a positive integer. On failure, it returns a negative errno-style error code.

.SS "Errors"

.PP Returned errors may indicate the following problems:

.PP **-EINVAL**

The *m* parameter is **NULL**.

.RE

.PP **-EBADMSG**

The message cannot be parsed.

.RE

.PP **-EPERM**

The message is not sealed.

.RE

.PP **-ENXIO**

The message end has been reached and the requested elements cannot be read.

.RE

.PP **-ENOMEM**

Memory allocation failed.

.RE

.SH "NOTES"

.PP Functions described here are available as a shared library, which can be compiled against and linked to with the **libsystemd** [**pkg-config**(1)](/man/os/systemd/pkg-config.1) file.

.PP All functions listed here are thread-agnostic and only a single thread may operate on a given object at any given time. Different threads may access the same object at different times. Multiple independent objects may be used from different threads in parallel.

.PP The code described here uses [**getenv**(3)](/man/os/systemd/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)](/man/os/systemd/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.

.SH "HISTORY"

.PP **sd\_bus\_message\_skip()** was added in version 240.

.SH "SEE ALSO"
