NAME¶

sd_bus_reply_method_return, sd_bus_reply_method_returnv - Reply to a D-Bus method call

SYNOPSIS¶

#include <systemd/sd-bus.h>

int sd_bus_reply_method_return(sd_bus_message *call, const char *types, ...);

int sd_bus_reply_method_returnv(sd_bus_message *call, const char *types, va_list ap);

DESCRIPTION¶

sd_bus_reply_method_return() sends a reply to the call message. The type string types and the arguments that follow it must adhere to the format described in sd_bus_message_append(3). If no reply is expected to call, this function succeeds without sending a reply.

RETURN VALUE¶

On success, this function returns a non-negative integer. On failure, it returns a negative errno-style error code.

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.
