Overview
The SetFilePosition function moves the current position to the start of a Basic File Object or an optionally specified position.
Syntax/Parameters
Syntax
int = SetFilePosition ( handle hBasicFile, [qword position ] );
Parameters
hBasicFile
A handle to a Basic File Object.
position
An optional qword containing a position from which the next read or write will apply. If omitted, the value will be zero.
Return Value
Returns an int as ERROR_NONE or a formatted error code on failure. Use the GetLastError function to retrieve error information.
Remarks
The SetFilePosition function does not return an error if the position parameter sets the file pointer beyond the end of the file. This enlarges the file, however, the size of the file does not increase until the TruncateFilePosition, WriteBlock or WriteLine functions are called. A write operation increases the size of the file to the position specified plus the size of the buffer written, which results in the intervening bytes being uninitialized.
