32 * A compilation database holds all information used to compile files in a
33 * project. For each file in the database, it can be queried for the working
34 * directory or the command line used for the compiler invocation.
36 * Must be freed by \c clang_CompilationDatabase_dispose
38 typedef void * CXCompilationDatabase;
41 * Contains the results of a search in the compilation database
43 * When searching for the compile command for a file, the compilation db can
44 * return several commands, as the file may have been compiled with
45 * different options in different places of the project. This choice of compile
46 * commands is wrapped in this opaque data structure. It must be freed by
47 * \c clang_CompileCommands_dispose.
49 typedef void * CXCompileCommands;
52 * Represents the command line invocation to compile a specific file.
54 typedef void * CXCompileCommand;

66 * Database can not be loaded

70 } CXCompilationDatabase_Error;
73 * Creates a compilation database from the database found in directory
74 * buildDir. For example, CMake can output a compile_commands.json which can
75 * be used to build the database.
77 * It must be freed by \c clang_CompilationDatabase_dispose.
