39 // The user can define the following macros in the build script to
40 // control Google Test's behavior. If the user doesn't define a macro
41 // in this list, Google Test will define it.
42 //
43 // GTEST_HAS_CLONE - Define it to 1/0 to indicate that clone(2)
44 // is/isn't available.
45 // GTEST_HAS_EXCEPTIONS - Define it to 1/0 to indicate that exceptions
46 // are enabled.
47 // GTEST_HAS_GLOBAL_STRING - Define it to 1/0 to indicate that ::string
48 // is/isn't available (some systems define
49 // ::string, which is different to std::string).
50 // GTEST_HAS_GLOBAL_WSTRING - Define it to 1/0 to indicate that ::string
51 // is/isn't available (some systems define
52 // ::wstring, which is different to std::wstring).
53 // GTEST_HAS_POSIX_RE - Define it to 1/0 to indicate that POSIX regular
54 // expressions are/aren't available.
55 // GTEST_HAS_PTHREAD - Define it to 1/0 to indicate that <pthread.h>
56 // is/isn't available.
57 // GTEST_HAS_RTTI - Define it to 1/0 to indicate that RTTI is/isn't
58 // enabled.
59 // GTEST_HAS_STD_WSTRING - Define it to 1/0 to indicate that
60 // std::wstring does/doesn't work (Google Test can
61 // be used where std::wstring is unavailable).
62 // GTEST_HAS_TR1_TUPLE - Define it to 1/0 to indicate tr1::tuple
63 // is/isn't available.
64 // GTEST_HAS_SEH - Define it to 1/0 to indicate whether the
65 // compiler supports Microsoft's "Structured
66 // Exception Handling".
67 // GTEST_HAS_STREAM_REDIRECTION
68 // - Define it to 1/0 to indicate whether the
69 // platform supports I/O stream redirection using
70 // dup() and dup2().
71 // GTEST_USE_OWN_TR1_TUPLE - Define it to 1/0 to indicate whether Google
72 // Test's own tr1 tuple implementation should be
73 // used. Unused when the user sets
74 // GTEST_HAS_TR1_TUPLE to 0.
75 // GTEST_LINKED_AS_SHARED_LIBRARY
76 // - Define to 1 when compiling tests that use
77 // Google Test as a shared library (known as
78 // DLL on Windows).
79 // GTEST_CREATE_SHARED_LIBRARY
80 // - Define to 1 when compiling Google Test itself
81 // as a shared library.
82 
83 // This header defines the following utilities:
84 //
85 // Macros indicating the current platform (defined to 1 if compiled on
86 // the given platform; otherwise undefined):
87 // GTEST_OS_AIX - IBM AIX
88 // GTEST_OS_CYGWIN - Cygwin
89 // GTEST_OS_HPUX - HP-UX
90 // GTEST_OS_LINUX - Linux

98 // GTEST_OS_WINDOWS_MINGW - MinGW
99 // GTEST_OS_WINDOWS_MOBILE - Windows Mobile
100 // GTEST_OS_ZOS - z/OS
101 //
102 // Among the platforms, Cygwin, Linux, Max OS X, and Windows have the
103 // most stable support. Since core members of the Google Test project
104 // don't have access to other platforms, support for them may be less
105 // stable. If you notice any problems on your platform, please notify
106 // googletestframework@googlegroups.com (patches for fixing them are
107 // even more welcome!).
108 //
109 // Note that it is possible that none of the GTEST_OS_* macros are defined.
110 //
111 // Macros indicating available Google Test features (defined to 1 if
112 // the corresponding feature is supported; otherwise undefined):

114 // tests)
115 // GTEST_HAS_DEATH_TEST - death tests
116 // GTEST_HAS_PARAM_TEST - value-parameterized tests

120 // GTEST_HAS_POSIX_RE (see above) which users can
121 // define themselves.
122 // GTEST_USES_SIMPLE_RE - our own simple regex is used;
123 // the above two are mutually exclusive.
124 // GTEST_CAN_COMPARE_NULL - accepts untyped NULL in EXPECT_EQ().
125 //
126 // Macros for basic C++ coding:
127 // GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning.
128 // GTEST_ATTRIBUTE_UNUSED_ - declares that a class' instances or a
129 // variable don't have to be used.
130 // GTEST_DISALLOW_ASSIGN_ - disables operator=.
131 // GTEST_DISALLOW_COPY_AND_ASSIGN_ - disables copy ctor and operator=.
132 // GTEST_MUST_USE_RESULT_ - declares that a function's result must be used.
133 //
134 // Synchronization:
135 // Mutex, MutexLock, ThreadLocal, GetThreadCount()
136 // - synchronization primitives.
137 // GTEST_IS_THREADSAFE - defined to 1 to indicate that the above
138 // synchronization primitives have real implementations
139 // and Google Test is thread-safe; or 0 otherwise.

142 // is_pointer - as in TR1; needed on Symbian and IBM XL C/C++ only.
143 // IteratorTraits - partial implementation of std::iterator_traits, which
144 // is not available in libCstd when compiled with Sun C++.

146 // Smart pointers:
147 // scoped_ptr - as in TR2.
148 //
149 // Regular expressions:
150 // RE - a simple regular expression class using the POSIX
151 // Extended Regular Expression syntax on UNIX-like
152 // platforms, or a reduced regular exception syntax on
153 // other platforms, including Windows.
154 //
155 // Logging:
156 // GTEST_LOG_() - logs messages at the specified severity level.
157 // LogToStderr() - directs all log messages to stderr.
158 // FlushInfoLog() - flushes informational log messages.
159 //
160 // Stdout and stderr capturing:
161 // CaptureStdout() - starts capturing stdout.
162 // GetCapturedStdout() - stops capturing stdout and returns the captured
163 // string.
164 // CaptureStderr() - starts capturing stderr.
165 // GetCapturedStderr() - stops capturing stderr and returns the captured
166 // string.
167 //
168 // Integer types:
169 // TypeWithSize - maps an integer to a int type.
170 // Int32, UInt32, Int64, UInt64, TimeInMillis

177 // GTEST_DEFINE_*() - defines a flag.

181 // GetEnv() - gets the value of an environment variable.
182 // BoolFromGTestEnv() - parses a bool environment variable.
183 // Int32FromGTestEnv() - parses an Int32 environment variable.
184 // StringFromGTestEnv() - parses a string environment variable.

988 // how do you know the pointer is really of type SubclassOfFoo? It
