CFile:FilePos

The FilePos method returns the byte offset of the file read/write pointer.

Syntax

nPos = CFile:FilePos()

nPos is the byte offset of the current file position.

On success, nPos is a number >= 0.

On failure, nPos = -1.

Remarks

The value returned by FilePos is a byte offset from the beginning of the file. If the file is translated to text mode when written to the file, then this value differs from the actual byte offset into the file.

Example

Suppose a CFile F exists and that the file is empty. The following script writes a string to it and then returns the file position after the write operation:

F:Seek(0,F.nBegin)	-- seek to the beginning of the file
F:Printf( "a string" )
Printf("pos = %d", F:FilePos() )	-- result: pos = 8
