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.Errors
Returned errors may indicate the following problems: -EINVALThe input parameter call is
NULL.
Message call is not a method call message.
Message call is not attached to a bus.
The error parameter e to sd_bus_reply_method_error() is not set,
see sd_bus_error_is_set(3).
-EPERM
Message call has been sealed.
-ENOTCONN
The bus to which message call is
attached is not connected.
-ENOMEM
Memory allocation failed.
In addition, any error returned by sd_bus_send(1) may be returned.
NOTES
These APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd pkg-config(1) file.SEE ALSO
