| 11 | //Each line has three parts separated by ":" |
| 12 | //<message id>:<file>:<line num> |
| 13 | //Where: |
| 14 | // <message id> is the message id to suppress. This equals to the "id" filed |
| 15 | // of the XML message record. |
| 16 | // <file> Is a file name. cppcheck understands the following wildcards: |
| 17 | // * matches any number of any characters |
| 18 | // ? a single character |
| 19 | // Note: please use '/' as directory separator. |
| 20 | // <line num> The line number for which the message shall be ignored. |
| 21 | // |
| 22 | //Example to convert an XML record to a line in thif file: |
| 23 | // <error id="invalidPrintfArgType_sint" severity="warning" msg="%d in format string (no. 1) requires 'int' but the argument type is 'unsigned int'." verbose="%d in format string (no. 1) requires 'int' but the argument type is 'unsigned int'." cwe="686"> |
