//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 &apos;int&apos; but the argument type is &apos;unsigned int&apos;." verbose="%d in format string (no. 1) requires &apos;int&apos; but the argument type is &apos;unsigned int&apos;." 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"/>
// </error>
// to
//invalidPrintfArgType_sint:*/tf-m/test/framework/test_framework.c:150
//

//This rule conflicts the our coding style document.
variableScope

//While cppcheck states to work fine with missing standard library files, it
//still reports a lot of errors regarding those.
//So, ignore these.
missingIncludeSystem

//Stos cppcheck report errors regarding supression rules. These seem to be
