This page provides an overview of each error code. You can suppress errors using the Suppressions Control Panel (see Customizing Options on Windows). The following sections provide a detailed description of each error including:

  • A brief explanation of what problem has been detected.
  • An example program that generates a similar error.
  • Output that would be generated by running the example, with annotations indicating what the various pieces of the diagnostic mean and how they should be interpreted in identifying your own problems. The exact appearance of the error message may depend on how Insure++ is currently configured.
  • A brief description of ways in which the problem might be eliminated.

Sometimes you will see values identified as <argument #> or <return> instead of names from your program. In this case, <argument n> refers to the nth argument passed to the current function (i.e., the argument where the error was detected), and <return> refers to a value returned from the function indicated.

(sign)Types differ only by sign, e.g., int vs. unsigned int(error)CompilationWindows/Unix
(compatible)

Fundamental types are different but they happen to have the same representation on the particular hardware in use, e.g., int vs. long on machines where both are 32-bits.

(error)CompilationWindows/Unix
(incompatible)Fundamental types are different, e.g., int vs. double(tick)CompilationWindows/Unix
(pointer)

This is not an error class, but a keyword used to suppress messages about mismatched pointer types, such as int * vs. char *.

(tick)CompilationWindows/Unix
(union)

Forces a declared union argument to match only a similar union as an actual argument. If this is suppressed, you may pass any of the individual union elements to the routine, rather than the union type, or pass a union to a routine which expects one of the union-elements as an argument.
