需要读取二进制.dat地图档只知WINAPI CreateFileA，ReadFile可以读但不知道在TC中指出参数怎么填才正确
用TC自带的文件读取只能读到标头的前几个字

原码如下:

function WH()
var path = "D:/BlueCrossgate/map/1/3/2160.dat"
var hFile = fileopen(path)
traceprint(hFile)
var content = ReadFile(hFile)
traceprint(content)
var FF = fileclose(hFile)
traceprint(FF)
end
function CreateFileA(lpFileName, dwDesiredAccess = #80000000, dwShareMode = #1, lpSecurityAttributes = null, dwCreationDisposition = 0, dwFlagsAndAttributes = #80, hTemplateFile = null)
//dwDesiredAccess
var GENERIC_READ = #80000000
//dwShareMode
var off = #0
var FILE_SHARE_DELETE = #00000004
var FILE_SHARE_READ = #00000001
var FILE_SHARE_WRITE = #00000002
//dwCreationDisposition
var OPEN_EXISTING = 3
return dllcall("kernel32.dll", "int", "CreateFileA", "char *", lpFileName, "int", dwDesiredAccess, "int", dwShareMode, "int", lpSecurityAttributes, "int", dwCreationDisposition, "int", dwFlagsAndAttributes, "int", hTemplateFile)
end
var tempcontent = 0
function ReadFile(hFile, lpOverlapped = null)
var nNumberOfBytesToRead = dllcall("kernel32.dll", "long", "GetFileSize", "long", hFile, "long", null)
tempcontent = 0
var lpBufferPointer = getvarpointer(tempcontent)
traceprint(lpBufferPointer)
var lpNumberOfBytesRead = 0
var lpNumberOfBytesReadaddr = getvarpointer(lpNumberOfBytesRead)
traceprint(lpNumberOfBytesReadaddr)
var CC = dllcall("kernel32.dll", "int", "ReadFile", "int", hFile, "int", lpBufferPointer, "int", nNumberOfBytesToRead, "int", lpNumberOfBytesReadaddr, "int", lpOverlapped)
traceprint(CC)
return tempcontent
end
function Closehandle(hObject)
return dllcall("kernel32.dll", "long", "CloseHandle", "long", hObject)
end
