The lint program checker has proven time and again to be one of the best tools for finding portability problems and certain types of coding errors in C programs. This book introduces you to lint, guides you through running it on your programs, and helps you to interpret lint's output. lint verifies a program or program segments against standard libraries, checks the code for common portability errors, and tests the programming against som tried and true guidelines. linting your code is a necessary (though not sufficient) step in writing clean, portable, effective programs.
