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.

HISTORY

       sd_bus_message_skip() was added in version 240.
