Boost.Thread uses several configuration macros in <boost/config.hpp>, as well as configuration macros meant to be supplied by the application. These macros are documented here.
These macros are defined by Boost.Thread but are expected to be used by application code.
| Macro | Meaning |
|---|---|
| BOOST_HAS_THREADS | Indicates that threading support is available. This means both that there is a platform specific implementation for Boost.Thread and that threading support has been enabled in a platform specific manner. For instance, on the Win32 platform there's an implementation for Boost.Thread but unless the program is compiled against one of the multithreading runtimes (often determined by the compiler predefining the macro _MT) the BOOST_HAS_THREADS macro remains undefined. |
These macros are defined by Boost.Thread and are implementation details of interest only to implementors.
| Macro | Meaning |
|---|---|
| BOOST_HAS_WINTHREADS | Indicates that the platform has the Microsoft Win32 threading libraries, and that they should be used to implement Boost.Thread. |
| BOOST_HAS_PTHREADS | Indicates that the platform has the POSIX pthreads libraries, and that they should be used to implement Boost.Thread. |
| BOOST_HAS_FTIME | Indicates that the implementation should use GetSystemTimeAsFileTime() and the FILETIME type to calculate the current time. This is an implementation detail used by boost::detail::getcurtime(). |
| BOOST_HAS_GETTTIMEOFDAY | Indicates that the implementation should use gettimeofday() to calculate the current time. This is an implementation detail used by boost::detail::getcurtime(). |
