question about auto reply

[monnand]

Dear all,

I'm writing a pidgin plugin, which implements something like an IM
robot. I use purple_conv_im_send_with_flags() to reply IM message.
However, no matter what flag I use in purple_conv_im_send_with_flags(),
the message sent by the bot will always be shown in the conversation window.

My question is: Does there any method which could send a message without
notifying the UI part, so the message sent by robot could be invisible
to users.

Thank you!
