Kimmo Varis dffe1a0acd Fix doxgen comment. 2011-01-13 23:25:17 +02:00
Kimmo Varis 4668e19060 Modify Cppcheck::addFile() only take one file as a parameter.
CLI and GUI already do the directory walking for us and we have list
of files to check. So we were duplicating this directory walking.
Practically doing check again for each file if it is a directory.
Which can take some time with large amount of files.

Pete Johns 502cfe7243 Fixed #2384 ("The function 's::f' can be const" reported for pointer-to-pointer)
Moved check for pointer variables into isVariableDeclaration()

Can now handle multiple scopes and multiple levels of indirection. Simplified check for strucs and unions, too, reducing the size of getVarList().

skipScopeIdentifiers() and skipPointers() should probably be methods on class Token.
