Recently, I used the Boost library for multi-thread development. It is visible that the compilation engineers in vs always encounter Macro redefinition errors, similar to the following error description. 1>c:\program files (x86)\microsoft visual studio 10.0\vc\include\stdint.h(116): warning C4005: 'INT8_C' : macro redefinition1> c:\vc\include\boost\cstdint.hpp(376) : see previous definition of 'INT8_C' At the beginning, I was not responsible

Windows. H and winsock2.h contain sequence. Generally, when using C ++ for network development on the Windows platform, these two header files are included at the same time. If the sequence is improper (windows. h prior to winsock2.h.

push_macro and # pragma pop_macro. The former pushes the specified macro into the stack, which is equivalent to temporary storage for future use. The latter pushes the macro at the top of the stack, and the pop-up macro will overwrite the macro with the same name as the current one.
