| // |
| // GTEST_HAS_CLONE - Define it to 1/0 to indicate that clone(2) |
| // is/isn't available. |
| // GTEST_HAS_EXCEPTIONS - Define it to 1/0 to indicate that exceptions |
| // are enabled. |
| // GTEST_HAS_GLOBAL_STRING - Define it to 1/0 to indicate that ::string |
| // is/isn't available (some systems define |
| // ::string, which is different to std::string). |
| // GTEST_HAS_GLOBAL_WSTRING - Define it to 1/0 to indicate that ::string |
| // is/isn't available (some systems define |
| // ::wstring, which is different to std::wstring). |
| // GTEST_HAS_POSIX_RE - Define it to 1/0 to indicate that POSIX regular |
| // expressions are/aren't available. |
| // GTEST_HAS_PTHREAD - Define it to 1/0 to indicate that <pthread.h> |
| // is/isn't available. |

| // enabled. |
| // GTEST_HAS_STD_WSTRING - Define it to 1/0 to indicate that |
| // std::wstring does/doesn't work (Google Test can |
| // be used where std::wstring is unavailable). |
| // GTEST_HAS_TR1_TUPLE - Define it to 1/0 to indicate tr1::tuple |
| // is/isn't available. |
| // GTEST_HAS_SEH - Define it to 1/0 to indicate whether the |
| // compiler supports Microsoft's "Structured |
| // Exception Handling". |
| // GTEST_HAS_STREAM_REDIRECTION |
| // - Define it to 1/0 to indicate whether the |
| // platform supports I/O stream redirection using |
| // dup() and dup2(). |
| // GTEST_USE_OWN_TR1_TUPLE - Define it to 1/0 to indicate whether Google |
| // Test's own tr1 tuple implementation should be |
| // used. Unused when the user sets |
| // GTEST_HAS_TR1_TUPLE to 0. |
| // GTEST_LINKED_AS_SHARED_LIBRARY |
| // - Define to 1 when compiling tests that use |
| // Google Test as a shared library (known as |
| // DLL on Windows). |
| // GTEST_CREATE_SHARED_LIBRARY |
| // - Define to 1 when compiling Google Test itself |
| // as a shared library. |
| |
| // This header defines the following utilities: |
| // |
| // Macros indicating the current platform (defined to 1 if compiled on |
| // the given platform; otherwise undefined): |
| // GTEST_OS_AIX - IBM AIX |
| // GTEST_OS_CYGWIN - Cygwin |
| // GTEST_OS_HPUX - HP-UX |

| // GTEST_OS_ZOS - z/OS |
| // |
| // Among the platforms, Cygwin, Linux, Max OS X, and Windows have the |
| // most stable support. Since core members of the Google Test project |
| // don't have access to other platforms, support for them may be less |
| // stable. If you notice any problems on your platform, please notify |
| // googletestframework@googlegroups.com (patches for fixing them are |
| // even more welcome!). |
| // |
| // Note that it is possible that none of the GTEST_OS_* macros are defined. |
| // |

| // GTEST_HAS_TYPED_TEST - typed tests |
| // GTEST_HAS_TYPED_TEST_P - type-parameterized tests |
| // GTEST_USES_POSIX_RE - enhanced POSIX regex is used. Do not confuse with |
| // GTEST_HAS_POSIX_RE (see above) which users can |

| // Macros for basic C++ coding: |
| // GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning. |
| // GTEST_ATTRIBUTE_UNUSED_ - declares that a class' instances or a |
| // variable don't have to be used. |
| // GTEST_DISALLOW_ASSIGN_ - disables operator=. |
| // GTEST_DISALLOW_COPY_AND_ASSIGN_ - disables copy ctor and operator=. |
| // GTEST_MUST_USE_RESULT_ - declares that a function's result must be used. |
| // |
| // Synchronization: |
| // Mutex, MutexLock, ThreadLocal, GetThreadCount() |
| // - synchronization primitives. |
| // GTEST_IS_THREADSAFE - defined to 1 to indicate that the above |
| // synchronization primitives have real implementations |
| // and Google Test is thread-safe; or 0 otherwise. |
| // |
| // Template meta programming: |
| // is_pointer - as in TR1; needed on Symbian and IBM XL C/C++ only. |
| // IteratorTraits - partial implementation of std::iterator_traits, which |
| // is not available in libCstd when compiled with Sun C++. |
| // |
| // Smart pointers: |
| // scoped_ptr - as in TR2. |
| // |
| // Regular expressions: |

| // Stdout and stderr capturing: |
| // CaptureStdout() - starts capturing stdout. |
| // GetCapturedStdout() - stops capturing stdout and returns the captured |
| // string. |
| // CaptureStderr() - starts capturing stderr. |
| // GetCapturedStderr() - stops capturing stderr and returns the captured |
| // string. |
| // |
| // Integer types: |
| // TypeWithSize - maps an integer to a int type. |
| // Int32, UInt32, Int64, UInt64, TimeInMillis |
| // - integers of known sizes. |
| // BiggestInt - the biggest signed integer type. |
| // |
| // Command-line utilities: |
| // GTEST_FLAG() - references a flag. |
| // GTEST_DECLARE_*() - declares a flag. |
| // GTEST_DEFINE_*() - defines a flag. |
| // GetArgvs() - returns the command line as a vector of strings. |

| // |
| // int foo; |
| // GTEST_COMPILE_ASSERT_(foo, msg); // not supposed to compile as foo is |
| // // not a compile-time constant. |

| // - By using the type CompileAssert<(bool(expr))>, we ensures that |

| // determined at compile-time.) |
| // |
| // - The outter parentheses in CompileAssert<(bool(expr))> are necessary |
| // to work around a bug in gcc 3.4.4 and 4.0.1. If we had written |
