Oracle equivalent to Ingres inquire_sql or inquire_ingres?

Question

I'm converting some legacy embedded-Ingres C code to work against Oracle. I've found references to functions "inquire_ingres()" and "inquire_sql()," which, per the docs at http://docs.ingres.com/ingres/9.3/sql-reference-guide/2275-inquiresql-function, allow a program to gather runtime information about the status and results of the last SQL statement that the program issued.

Does Oracle provide similar convenience functionality, or am I going to have to just paw around some more in the innards of sqlca as I suspect I'm going to?
