Fprintf issue

i had to send a mail an attachment which i got from find command.
But i did not get mail but could see the following line in the logs "aliased to fprintf.c". Can someone help me to understand what does it mean?..As this issue is not occuring now, i could not replicate the problem now.Thanks.

unix - Shell Script Error: "aliased to fprintf.cName.ksh[324] 121234 IOT/Abort" - IQwen question AND answer Was a shell alias involved?
