This error notice is one of the few SNACs that can be sent to the host and received by a client.

The SNAC can come from either origin source, this is because the message is basically forwarded from the source client, to the server, to the destination client.

This SNAC may only be sent as a programmatic response to an inter-client message. It is used to indicate that there was some problem with the original message received by the sender. If this SNAC is not immediately generated as a response, the client loses the right to send it at all and attempts to send it will be rejected by the server.

As transmitted, "cookie", "channel", and "username" are to be those which were presented in the inter-client message being rejected. As received, "username" has been changed to indicate the source of the error. It is not allowed to respond to a CLIENT_ERR SNAC with another CLIENT_ERR SNAC. Receiving a CLIENT_ERR SNAC does not grant the right to EVIL.

SNAC List

Subgroup Origin Name 0x0001 Any ICBM__ERR This is the error SNAC for the ICBM foodgroup. 0x0002 Client ICBM__ADD_PARAMETERS This SNAC is typically sent prior to sending the OSERVICE__CLIENT_ONLINE so that the host is properly initialized with the clients' preferences. 0x0003 Client ICBM__DEL_PARAMETERS These are the delete all parameters for a given channel. 0x0004 Client ICBM__PARAMETER_QUERY This SNAC requests ICBM parameters from the host. 0x0005 Host ICBM__PARAMETER_REPLY This SNAC is sent by the host in response to a ICBM__PARAMETER_QUERY. 0x0006 Client ICBM__CHANNEL_MSG_TOHOST This is the basic inter-client message after which the group was named (Inter-Client Basic Messages). 0x0007 Host ICBM__CHANNEL_MSG_TOCLIENT This is the ICBM__CHANNEL_MSG_TOHOST after it has been reformatted by the host and sent to the destination client. 0x0008 Client ICBM__EVIL_REQUEST This requests that the specified user is sent an EVIL notification. 0x0009 Host ICBM__EVIL_REPLY The reply tells the requester, the sender of an ICBM__EVIL_REQUEST SNAC, how much EVIL, if any, was applied to the recipient. 0x000A Host ICBM__MISSED_CALLS When the host is unable to send one or more messages to the client, the host sends this SNAC to the client to let it know that it missed some messages ("calls"). 0x000B Any ICBM__CLIENT_ERR This error notice is one of the few SNACs that can be sent to the host and received by a client. 0x000C Host ICBM__HOST_ACK This SNAC is sent by the host upon receipt of any ICBM__CHANNEL_MSG_TOHOST which includes the optional ICBM__TLV_TAGS_REQUEST_HOST_ACK TLV. 0x000D NCD ICBM__SIN_STORED This is not currently documented.
