| //This file contains suppression rules for CppCheck. |
| //C style comments can be used. |
| // |
| //Each line has three parts separated by ":" |
| //<message id>:<file>:<line num> |
| //Where: |
| // <message id> is the message id to suppress. This equals to the "id" filed |
| // of the XML message record. |
| // <file> Is a file name. cppcheck understands the following wildcards: |
| // * matches any number of any characters |
| // ? a single character |
| // Note: please use '/' as directory separator. |
| // <line num> The line number for which the message shall be ignored. |
| // |
| //Example to convert an XML record to a line in thif file: |
| // <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"> |
| // <location file0="C:\work\tf-m\test\framework\test_framework.c" file="C:\work\tf-m\test\framework\test_framework.c" line="150"/> |
