TruncateFile Method

Truncates a file to a given size.

Syntax

bool __fastcall TruncateFile(String FilePath, __int64 NewSize);

Remarks

This method truncates the file at FilePath to the given NewSize (specified in bytes). NewSize must not be less than 0 or greater than the file's current size.

This method returns true if the file has been truncated successfully and is immediately ready for further modifications.

This method returns false if the server is still in the process of truncating the file (this could happen, e.g., if the server needs to truncate multiple replicas of the file). In this case, the server will reject any further attempts to modify the file until it has finished truncating it. Monitor the file's size using GetResourceInfo to determine when the truncation process has finished.
