Standard features Whereas a compiler concerns itself primarily with code generation, lint is completely devoted to checking your code for a myriad of possible defects. Getting the lint out Notwithstanding the slightly contrived example above, what sort of real world benefit can you expect from addressing all of the warnings produced by lint? My experiences on a Intro - Lint (3) - Lint (CD) project involving a small microcontroller total code size below 32KB included the following: Lint found two or three outright bugs-before I had even started testing the code.
I learned something about the C language each time I ran it. My final code was cleaner because lint informed me of unused variables, macros, and header Intro - Lint (3) - Lint (CD) includes that could be safely removed. I was better informed of potential portability issues. Figure 1: How lint fits into the development process It's worth looking at where lint fits into the development process.

The lint program also recognizes the pragmas related to type-based alias-disambiguation documented in this chapter. In the following example, the pointer p of type integer is cast as a pointer of type struct foo. In the following example, the void pointer vpis cast as a struct pointer.
In the following example, the address of structure member foo. In the following example, the pointer f1 of type struct fooa is being cast as a pointer of type struct foob. In addition, at alias levels standard and strongthe assumptions is that the tags must match for aliasing to occur.
Use pragma alias struct fooastruct foob before the assignment to f1 and lint stops generating the warning. Search Scope:. Document Information Preface 1.
