LP is actually “Long Pointer”, which means 32 bits. Why is that called a long pointer? Because that’s what a long pointer was on win16. Same reason a DWORD (double word) is also 32 bits, because a word was 16 bits.
I haven’t really done much with coding 64 bit Windows applications so I don’t if it’s the same, but Windows 16 bit roots was very obvious in win32.
Identifying the windows string types is fun. The letters are supposed to have a meaning. Without looking them up, my guess is:
LP_ - Length Prepended
C_STR - C string / null-terminated
WSTR - “Wide” string / utf-16
TSTR - I have no idea

I have no idea what the “T” stands for, but TSTR refers to either a Wide or ANSI string depending on whether the UNICODE symbol is defined
