SD_BUS_MESSAGE_SKIP(3) sd_bus_message_skip SD_BUS_MESSAGE_SKIP(3)
NAME
sd_bus_message_skip - Skip elements in a bus message
SYNOPSIS
#include <systemd/sd-bus.h>
int sd_bus_message_skip(sd_bus_message *m, const char* types);
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.
NOTES
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.
