在字符错误 C2440 中转换 LPVOID：=

Question

How do I convert a LPVOID to char ?

char * pCacheMap;

pCacheMap = MapViewOfFile(hCacheMapping,FILE_MAP_READ|FILE_MAP_WRITE,0,0,0);

Error:

    3   IntelliSense: a value of type "LPVOID" cannot be assigned to an entity of type "char *" 
Error   1   error C2440: '=' : cannot convert from 'LPVOID' to 'char *' 

Answer 1

Use a cast. Since LPVOID is a synonym for void * it is legal to cast it to any other pointer type so:

pCacheMap = static_cast<char *>(MapViewOfFile(...)); 

will work.
