转换LPVOID IN CHAR ERROR C2440：=

Question

如何将LPVOID转换为char？

char * pCacheMap;

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

错误：

    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

使用演员。由于LPVOID是void *的同义词，因此将其强制转换为任何其他指针类型是合法的：

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

会奏效。
