I am using Pro*C. I am trying to find where a function is defined. I have searched the sqlca.h file. I have searched the $ORACLE_HOME/precomp/public directory. I have commented out all of my #include which was recommended somewhere else. The only thing left is the EXEC SQL INCLUDE SQLCA; which would break everything since I have a cursor and sql commands. The only thing in my program is a Function prototypes which has no function definition in it. I would like to edit the function to add more functionality to it.
