codeql/cpp-all 4.0.3-dev (changelog, source)

Module Strcat

Provides implementation classes modeling strcat and various similar functions. See semmle.code.cpp.models.Models for usage information.

import semmle.code.cpp.models.implementations.Strcat

Imports

ArrayFunction	Provides an abstract class for accurate modeling of input and output buffers in library functions when source code is not available. To use this QL library, create a QL class extending `ArrayFunction` with a characteristic predicate that selects the function or set of functions you are trying to model. Within that class, override the predicates provided by `ArrayFunction` to match the flow within that function. Finally, add a private import statement to `Models.qll`
DataFlow	Provides an abstract class for accurate dataflow modeling of library functions when source code is not available. To use this QL library, create a QL class extending `DataFlowFunction` with a characteristic predicate that selects the function or set of functions you are modeling. Within that class, override the predicates provided by `DataFlowFunction` to match the flow within that function.
NonThrowing	Provides an abstract class for modeling functions that never throw.
SideEffect	Provides an abstract class for accurate dataflow modeling of library functions when source code is not available. To use this QL library, create a QL class extending `SideEffectFunction` with a characteristic predicate that selects the function or set of functions you are modeling. Within that class, override the predicates provided by `SideEffectFunction` to match the flow within that function.
Taint	Provides an abstract class for accurate taint modeling of library functions when source code is not available. To use this QL library, create a QL class extending `TaintFunction` with a characteristic predicate that selects the function or set of functions you are modeling. Within that class, override the predicates provided by `TaintFunction` to match the flow within that function.

Classes

StrcatFunction	The standard function `strcat` and its wide, sized, and Microsoft variants.
StrlcatFunction	The `strlcat` function.
