Windows Mobile process viewer development (4)-view memory, internal storage and memory card usage

The content of the first three lectures is not detailed, because it was previously done, so we probably copied it.CodeI also learned some of the functions to be implemented, so I will give them a little more details.

 

Function used to obtain the current storage Information

 

Bool winapi globalmemorystatus (_ inout lpmemorystatusex lpbuffer );

 

Lpbuffer is a memorystatus struct that obtains the current storage information.

 

Typedef struct _ memorystatus {
DWORD dwlength;
DWORD dwmemoryload;
DWORD dwtotalphys;
DWORD dwavailphys;
DWORD dwtotalpagefile;
DWORD dwavailpagefile;
DWORD dwtotalvirtual;
DWORD dwavailvirtual;
} Memorystatus, * lpmemorystatus;
