32 // Low-level types and utilities for porting Google Mock to various
33 // platforms. All macros ending with _ and symbols defined in an
34 // internal namespace are subject to change without notice. Code
35 // outside Google Mock MUST NOT USE THEM DIRECTLY. Macros that don't
36 // end with _ are part of Google Mock's public API and can be used by
37 // code outside Google Mock.

49 // Note to maintainers: to reduce code duplication, prefer adding
50 // portability utilities to Google Test's gtest-port.h instead of
51 // here, as Google Mock depends on Google Test. Only add a utility
52 // here if it's truly specific to Google Mock.

57 // To avoid conditional compilation everywhere, we make it
58 // gmock-port.h's responsibility to #include the header implementing
59 // tr1/tuple. gmock-port.h does this via gtest-port.h, which is
60 // guaranteed to pull in the tuple header.
