You can call the function as is, because LPSTR is typedef'd as 'char*' and LPCTSTR as 'const char *', which does not need any expilcit type casting. I.E.

CString str = "Hello, world...";
LPSTR search = ",";
CString subStr = str.SpanExcluding( search );// expects LPCTSTR but needs no cast

When you don't use UNICODE, simply typecast it. If not, you'll have to convert it into a UNICODE string first:

LPCTSTR ANSI2UNICODE (char*    pszANSI)
{
static TCHAR awc[ MAX_SIZE];

MultiByteToWideChar ( CP_ACP,
0,
pszANSI,
-1,
awc
lstrlen (pszANSI) + 1
);

return ( awc);
}

Maybe I rather ask you in more direct way.

Actually, I want to pass a variable typed LPSTR of  hFile to bcp_init ? It seems that it cannot work, so, any problem in it ?

Can you specify 'it seems that it cannot work' a bit more detailed?
Do you get compiler or linker errors or does your code crash or hang?
Perhaps you could also add a small code fragment.
