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
-EBADMSG
-EPERM
-ENXIO
-ENOMEM
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.
