Get APi from the address

[ahmadmansoor]

we always do this to get the API addresss

GetAPIAddress = GetProcAddress(GetModuleHandle("Kernel.dll),FunctionName)

to get the Address of the API .
but what the programmatic way to get the API of the address .
like if we have this :

2FEB1344 >7611FC28 (��v kernel32.LockFile

if I have 2FEB1344 how I could know for which API it relative too !!

( I need the reverse way of GetProcAddress )
Thanks in adv
