The C Interface to Clang provides a relatively small API that exposes facilities for parsing source code into an abstract syntax tree (AST), loading already-parsed ASTs, traversing the AST, associating physical source locations with elements within the AST, and other facilities that support Clang-based development tools.

Modules | |
CompilationDatabase functions | |
String manipulation routines | |
File manipulation routines | |
Physical source locations | |
Clang represents physical source locations in its abstract syntax tree in great detail, with file, line, and column information for the majority of the tokens parsed in the source code. These data types and functions are used to represent source location information, either for a particular point in the program or for a range of points in the program, and extract specific location information from those data types. | |
Diagnostic reporting | |
Translation unit manipulation | |
The routines in this group provide the ability to create and destroy translation units from files, either by parsing the contents of the files or by reading in a serialized representation of a translation unit. | |
Cursor manipulations | |
Mapping between cursors and source code | |
Cursors represent a location within the Abstract Syntax Tree (AST). These routines help map between cursors and the physical locations where the described entities occur in the source code. The mapping is provided in both directions, so one can map from source code to the AST and back. | |
Type information for CXCursors | |
Information for attributes | |
Traversing the AST with cursors | |
These routines provide the ability to traverse the abstract syntax tree using cursors. | |
Cross-referencing in the AST | |
These routines provide the ability to determine references within and across translation units, by providing the names of the entities referenced by cursors, follow reference cursors to the declarations they reference, and associate declarations with their definitions. | |
Name Mangling API Functions | |
Module introspection | |
The functions in this group provide access to information about modules. | |
C++ AST introspection | |
The routines in this group provide access information in the ASTs specific to C++ language features. | |
Token extraction and manipulation | |
The routines in this group provide access to the tokens within a translation unit, along with a semantic mapping of those tokens to their corresponding cursors. | |
Debugging facilities | |
These routines are used for testing and debugging, only, and should not be relied upon. | |
Code completion | |
Code completion involves taking an (incomplete) source file, along with knowledge of where the user is actively editing that file, and suggesting syntactically- and semantically-valid constructs that the user might want to use at that particular point in the source code. These data structures and routines provide support for code completion. | |

The C Interface to Clang provides a relatively small API that exposes facilities for parsing source code into an abstract syntax tree (AST), loading already-parsed ASTs, traversing the AST, associating physical source locations with elements within the AST, and other facilities that support Clang-based development tools.
This C interface to Clang will never provide all of the information representation stored in Clang's C++ AST, nor should it: the intent is to maintain an API that is relatively stable from one release to the next, providing only the basic functionality needed to support development tools.
To avoid namespace pollution, data types are prefixed with "CX" and functions are prefixed with "clang_".

CXCursor_TypeRef | A reference to a type declaration. A type reference occurs anywhere where a type is named but not declared. For example, given: typedef unsigned size_type;
size_type size;
The typedef is a declaration of size_type (CXCursor_TypedefDecl), while the type of the variable "size" is referenced. The cursor referenced by the type of size is the typedef for size_type. |

CXCursor_OverloadedDeclRef | A reference to a set of overloaded functions or function templates that has not yet been resolved to a specific function or function template. An overloaded declaration reference cursor occurs in C++ templates where a dependent name refers to a function. For example: template<typename T> void swap(T&, T&);

void swap(X&, X&);
template<typename T>
void reverse(T* first, T* last) {
while (first < last - 1) {
swap(*first, *--last);
++first;
}
}
struct Y { };
void swap(Y&, Y&);
Here, the identifier "swap" is associated with an overloaded declaration reference. In the template definition, "swap" refers to either of the two "swap" functions declared above, so both results will be available. At instantiation time, "swap" may also refer to other functions found via argument-dependent lookup (e.g., the "swap" function at the end of the example). The functions |

Enumerator | |
---|---|
CXGlobalOpt_None | Used to indicate that no special CXIndex options are needed. |

CINDEX_LINKAGE CXIndex clang_createIndex | ( | int | excludeDeclarationsFromPCH, |
int | displayDiagnostics | ||
) |
Provides a shared context for creating translation units.
It provides two options:
Here is an example:
This process of creating the 'pch', loading it separately, and using it (via -include-pch) allows 'excludeDeclsFromPCH' to remove redundant callbacks (which gives the indexer the same performance benefit as the compiler).
CINDEX_LINKAGE unsigned clang_CXIndex_getGlobalOptions | ( | CXIndex | ) |
Gets the general options associated with a CXIndex.
CINDEX_LINKAGE void clang_CXIndex_setGlobalOptions | ( | CXIndex | , |
unsigned | options | ||
) |
Sets general options associated with a CXIndex.
For example:
options | A bitmask of options, a bitwise OR of CXGlobalOpt_XXX flags. |
CINDEX_LINKAGE void clang_CXIndex_setInvocationEmissionPathOption | ( | CXIndex | , |
const char * | Path | ||
) |
Sets the invocation emission path option in a CXIndex.
The invocation emission path specifies a path which will contain log files for certain libclang invocations. A null value (default) implies that libclang invocations are not logged..
CINDEX_LINKAGE void clang_disposeIndex | ( | CXIndex | index | ) |
Destroy the given index.
The index must not be destroyed until all of the translation units created within that index have been destroyed.
