Имя (Name)
sd_bus_message_rewind - Return to beginning of message or current
container
Синопсис (Synopsis)
#include <systemd/sd-bus.h>
int sd_bus_message_rewind(sd_bus_message *m, int complete);
Описание (Description)
sd_bus_message_rewind() moves the "read pointer" in the message m
to either the beginning of the message (if complete is true) or
to the beginning of the currently open container. If no container
is open, complete has no effect.
Возвращаемое значение (Return value)
On success, this function returns 0 or a positive integer. The
value is zero if the current container or whole message in case
no container is open is empty, and positive otherwise. On
failure, it returns a negative errno-style error code.
Errors
Returned errors may indicate the following problems:
-EINVAL
The m parameter is NULL.
-EPERM
The message m has not been sealed.
