| /* |
| * example.c |
| * |
| * Calculate the sum of a given range of integer numbers. The range is |
| * specified by providing two integer numbers as command line argument. |
| * If no arguments are specified, assume the predefined range [0..9]. |
| * Abort with an error message if the resulting number is too big to be |
| * stored as int variable. |
| * |
| * This program example is similar to the one found in the GCOV documentation. |
| * It is used to demonstrate the HTML output generated by LCOV. |
| * |
| * The program is split into 3 modules to better demonstrate the 'directory |
| * overview' function. There are also a lot of bloated comments inserted to |
| * artificially increase the source code size so that the 'source code |
| * overview' function makes at least a minimum of sense. |
