NAME¶

sd_bus_reply_method_error, sd_bus_reply_method_errorf, sd_bus_reply_method_errorfv, sd_bus_reply_method_errno, sd_bus_reply_method_errnof, sd_bus_reply_method_errnofv - Reply with an error to a D-Bus method call

SYNOPSIS¶

#include <elogind/sd-bus.h>

int sd_bus_reply_method_error(sd_bus_message *call, const sd_bus_error *e);

int sd_bus_reply_method_errorf(sd_bus_message *call, const char *name, const char *format, ...);

int sd_bus_reply_method_errorfv(sd_bus_message *call, const char *name, const char *format, va_list ap);

int sd_bus_reply_method_errno(sd_bus_message *call, int error, const sd_bus_error *p);

int sd_bus_reply_method_errnof(sd_bus_message *call, int error, const char *format, ...);

int sd_bus_reply_method_errnofv(sd_bus_message *call, int error, const char *format, va_list ap);

DESCRIPTION¶

The sd_bus_reply_method_error() function sends an error reply to the call message. The error structure e specifies the error to send, and is used as described in sd_bus_message_new_method_error(3). If no reply is expected to call, this function succeeds without sending a reply.

The sd_bus_reply_method_errorf() is to sd_bus_reply_method_error() what sd_bus_message_new_method_errorf() is to sd_bus_message_new_method_error().

The sd_bus_reply_method_errno() is to sd_bus_reply_method_error() what sd_bus_message_new_method_errno() is to sd_bus_message_new_method_error().

The sd_bus_reply_method_errnof() is to sd_bus_reply_method_error() what sd_bus_message_new_method_errnof() is to sd_bus_message_new_method_error().

RETURN VALUE¶

This function returns a non-negative integer if the error reply was successfully sent or if call does not expect a reply. 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 libelogind pkg-config(8) file.
