QuestionError: Cannot convert from 'std::map<_Kty,_Ty> *' to 'LPCTSTR' [modified] Pin

Hello,

I have a created a map named mapList
std::map<string, std::vector<FileInfo*>> mapList;
and loading to key and value.

when i try to create a view of the file in the process address space (MapViewOfFile) which returns a pointer to the file view.

error C2440: '=' : cannot convert from 'std::map<_Kty,_Ty> *' to 'LPCTSTR' msg is thrown

I think there is an error in typecasting from 'std::map&lt;_Kty,_Ty&gt; *' to 'LPCTSTR' as i'm implementing in below manner.
pBuf = (std::map<string, FileInfo*> *)MapViewOfFile(hMapSharedMemory, FILE_MAP_ALL_ACCESS, 0, 0, 0);

Can anyone suggest me a solution.

Thanks in advance,

Regards,
Mayur M
