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.

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.

History

sd_bus_message_skip() was added in version 240.
