+ *
+ * static int func(void)
+ * {

+ * File: dummy.c Line: 124 Column: 12

+ * File: somefile.c Line: 3 Column: 12
+ *
+ * \param location the location within a source file that will be decomposed
+ * into its parts.
+ *
+ * \param filename [out] if non-NULL, will be set to the filename of the
+ * source location. Note that filenames returned will be for "virtual" files,
+ * which don't necessarily exist on the machine running clang - e.g. when
+ * parsing preprocessed output obtained from a different environment. If
+ * a non-NULL value is passed in, remember to dispose of the returned value
+ * using \c clang_disposeString() once you've finished with it. For an invalid
+ * source location, an empty string is returned.
+ *
+ * \param line [out] if non-NULL, will be set to the line number of the
+ * source location. For an invalid source location, zero is returned.
+ *
+ * \param column [out] if non-NULL, will be set to the column number of the
+ * source location. For an invalid source location, zero is returned.
