3.7.3.14.5 Description

The userlog() method writes a message to the user log (ULOG) file. Messages are appended to the ULOG file with a tag made up of the time (hhmmss), system name, process name, and process-id of the invoking process. The tag is terminated with a colon.

We recommend that server applications limit their use ofuserlog() messages to messages that can be used to help debug application errors; flooding the ULOG file with incidental information can make it difficult to spot actual errors.
