Read the xml content from an .awcav preset; something like: file_read (filename, &data &len); Create the compressed data buffer and set the max len Compressed data must be always shorter in size, so len is long enough zip_buf = new UCHAR[len]; zip_len = len;

Compress the data aw_zip (zip_buf, &zip_len, data, len);

Set all attributes necessary aw_int_set (AW_CAV_CITIZEN, citizen); aw_int_set (AW_CAV_SESSION, session); aw_data_set (AW_CAV_DEFINITION, (const char*)zip_buf, zip_len); In case it is a universe CAV, the bot must be uni-admin to change other's uni-CAVs but always can change his own universe-CAV, using: aw_cav_change ();

In case it is a world CAV, the bot must be CT to change other's world-CAVs but always can change his own world-CAV, using: aw_world_cav_change ();

Once the preset is uploaded, set the avatar to CUSTOM_AVATAR (type = 65534) or to CUSTOM_WORLD_AVATAR (type = 65533) using either: aw_state_change () for your own avatar or aw_avatar_set (session) for other's avatars.

To request a CAV definition from the universe, use: aw_cav_request (citizen, session);

To request a CAV defintion from the world, use: aw_world_cav_request (citizen, session);
