erc-display-line

erc-display-line is a compiled Lisp function in `erc.el'.

(erc-display-line STRING &optional BUFFER)

Display STRING in the ERC BUFFER.
All screen output must be done through this function. If BUFFER is nil
or omitted, the default ERC buffer for the `erc-session-server' is used.
The BUFFER can be an actual buffer, a list of buffers, 'all or 'active.
If BUFFER = 'all, the string is displayed in all the ERC buffers for the
current session. 'active means the current active buffer
(`erc-active-buffer'). If the buffer can't be resolved, the current
buffer is used. `erc-display-line-1' is used to display STRING.

If STRING is nil, the function does nothing.
