what's the differnece between c++ function(fileseek) and api

[chiwing]

as i open the api manual , i can't find fileseek --> i am just recover fileseek is not a api, and i search fileseek in google, it say that it is a c++ function~ ~

what include need to load when call fileseek?

as i infer: we don't know the api source code , and can't modify it, except hook api~ ~

and c++ function , it's a open source function, that can be modify by coder

am i right?

I know of no such function.

If you want to seek on streams, use istream::seekg() on input streams
http://www.cplusplus.com/reference/iostream/istream/seekg/
and ostream::seekp() on output streams
http://www.cplusplus.com/reference/iostream/ostream/seekp/


If you are using the Windows API, the function is SetFilePointer()

The difference is that the first two work on C++ file stream objects, whereas the latter works with a low-level Windows file handle. The former are friendlier to use.

Hope this helps.

fileseek: it is borland c++ function --> VCL library function

Ah, now we're getting somewhere.

Its in SysUtils.


BDS comes with pretty extensive documentation. Load it up and type "fileseek" into the search box and it will give you all the information you want.

Hope this helps.
