The easiest thing for you is to order the Windows DDK which includes
headers and import libraries etc for ntdll.dll API functions. The price
for Windows DDK is only shipping costs.

Note that in usermode the Zw*** functions are called Nt*** so this
function would be called NtQuerySystemInformation() in the headers.
