LPCSTR - L‌ong P‌ointer to a C‌onst T‌CHAR string

LPCTSTR = L‌ong P‌ointer to a C‌onst T‌CHAR STR‌ing (Don't worry, a long pointer is the same as a pointer. There were two flavors of pointers under 16-bit windows.)

Here's the table:

• LPSTR = char*
• LPCSTR = const char*
• LPWSTR = wchar_t*
• LPCWSTR = const wchar_t*
• LPTSTR = char* or wchar_t* depending on _UNICODE
• LPCTSTR = const char* or const wchar_t* depending on _UNICODE
