10
11 int sd_bus_message_skip(sd_bus_message *m, const char* types);
12
14 sd_bus_message_skip() is somewhat similar to sd_bus_message_read(3),
15 but instead of reading the contents of the message, it only moves the
16 "read pointer". Subsequent read operations will read the elements that
17 are after the elements that were skipped.
18
19 The types argument has the same meaning as in sd_bus_message_read(). It
20 may also be NULL, to skip a single element of any type.
21
23 On success, sd_bus_message_skip() returns 0 or a positive integer. On
24 failure, it returns a negative errno-style error code.
25
26 Errors
27 Returned errors may indicate the following problems:
28
29 -EINVAL
30 The m parameter is NULL.
31
32 -EBADMSG
33 The message cannot be parsed.
34
35 -EPERM
36 The message is not sealed.
37
38 -ENXIO
39 The message end has been reached and the requested elements cannot
40 be read.
41
42 -ENOMEM
43 Memory allocation failed.

46 Functions described here are available as a shared library, which can
47 be compiled against and linked to with the libsystemd pkg-config(1)
48 file.
49
50 The code described here uses getenv(3), which is declared to be not
51 multi-thread-safe. This means that the code calling the functions
52 described here must not call setenv(3) from a parallel thread. It is
53 recommended to only do calls to setenv() from an early phase of the
54 program when no other threads have been started.
