What does the prefixes in API calls tell me?

Could you explain what the prefixes in API calls means?

E.G. nDrive, hFile, lpCreationTime, lpszLongPath and fPictureOwnsHandle.
What does the n, h, lp, lpsz and f mean?

The prefix is the type of the variable and it's purpose:

n - Integer variable, though in 32 bit windows it will mean long
h - handle of an object - file, window, ect.., also long
lp - pointer to something, usualy a string or a type
lpsz - pointer to a string, string type for VB
f - flags, specifies that the variable is a bitfield that hold the characteristics for an object or for something else, usualy 32bit
