I have a program that loads an Oracle shared object, after performing a truss on the process I noticed that Oracle is not closing all the files it is opening, thus after numerous iterations (255 unclosed file handles) the program quits responding to any future file requests... Thus I want to attempt to close these left open file handles after they are done being used... I have read about a function fcloseall() that should help in accomplishing what I am trying to do, however, I can not get it to work on Solaris 8... At compile time I get an undefined symbol... Does anyone either know how to get fcloseall() to work on Solaris, or have a piece of code that will accomplish this (i.e. closing all file handles generated by the current proces or subprocesses)?
