        A function call to fopen or open must be matched with a call to fclose or close, respectively.

        Why is this an issue?

        What is the potential impact?

        How can I fix it?

        More Info

        The standard C library provides fopen and the system call open to open and possibly create files. Each call to one of these functions must be matched with a respective call to fclose or close.

        Failing to close files that have been opened may lead to using up all of the OS’s file handles.
