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.
