將LPVOID轉換爲CHAR ERROR C2440：=

Question

如何將LPVOID轉換爲char？

char * pCacheMap; 

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

錯誤：

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

使用強制。由於LPVOID是void *的同義詞，因此將其轉換爲任何其他指針類型是合法的：

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

將起作用。
