The function is defined as follows:

// Query the date and time of the file
Function ulong closehandle (ulong hobject) Library "kernel32.dll" alias for "closehandle; ANSI"

Function ulong openfile (ref string lpfilename, ref ofstruct lpreopenbuff, ulong wstyle) Library "kernel32.dll" alias for "openfile; ANSI"
Function ulong filetimetosystemtime (ref filetime lpfiletime, ref systemtime lpsystemtime) Library "kernel32.dll" alias for "filetimetosystemtime; ANSI"
Function ulong getfiletime (ulong hfile, ref filetime lpcreationtime, ref filetime lplastaccesstime, ref filetime lplastwritetime) Library "kernel32.dll" alias for "getfiletime; ANSI"
// Search for files
Function long findfirstfile (string lpfilename, ref win32_find_data lpfindfiledata) Library "Kernel32" alias for "findfirstfilea; ANSI"

Function long findnextfile (long hfindfile, ref win32_find_data lpfindfiledata) Library "Kernel32" alias for "findnextfilea; ANSI"
Function long findclose (long hfindfile) Library "Kernel32" alias for "findclose; ANSI"
Function long getlasterror () Library "Kernel32" alias for "getlasterror; ANSI"
