Four-byte aligned compilation:

#pragmaPack (4)//set to 4-byte alignmenttypedefstruct_batterystatus_tag {system_power_status_ex2 sps;        WORD Wmainlevels;        WORD Wbackuplevels;        BOOL Fsupportschange; BOOL fchanged;} Battery_status,*Pbattery_status;#pragmaPack ()//Restore default Alignment/*=========================================================================================================== ============ #pragma pack (n): Each compiler on a particular platform has its own default "alignment factor" (also known as Zimo number). Programmers can change this factor by precompiling the command #pragma pack (n), where n is the "alignment factor" you want to specify. If n in #pramga pack (n) is greater than the number of bytes occupied by any member of the struct member, the n value is invalid. The compiler chooses the number of bytes of the largest data member in the struct as the basis for its memory byte alignment mechanism, in order to minimize the number of memory reads. The CPU reads faster than the memory read speed at least one order of magnitude, to save the operation takes time, will sacrifice the space to exchange the time. When storing, see if the next member can be stored in the same aligned byte as the current member, and if not, open another byte of alignment space. =============================================================================================================== ===========*/
