Often physically sets the file size for the specified instruction at the current file pointer position.

The physical size of the file can also be referred to as the end of the file. The SetEndOfFile target can be used to shorten or expand a file. If you are setting the logical end of a file, use the SetFileValidData function.

Syntax

  BOOL SetEndOfFile (  [in] HANDLE hfile); 

Parameters

The file should be fantastically created with GENERIC_WRITE access. For more information see File security in addition to permissions . Value

  • File size: Probably the size of the data in the file in bytes.
  • Selection size: volumeThe amount of space normally allocated for a file on a real hard disk, which is always a multiple of the cluster size.
  • Marketing Information Actual Length: The length of the file type data actually written in bytes. This rating is always less than or equal to the file size.

vSetEndOfFile The function sets the total file size. Use SetFileValidData to no doubt set the length of the data to be valid.

If
CreateFileMapping is called, which can create a file mapping object for hFile. First you need to call unmapviewoffile to cancel all views as a call CloseHandle to close the file association target before you can callSetEndOfFile.

Transactional Processes

If the return is associated with a handle, the end of the file position being modified is finalized.

  • File size: This is the size of the data in each file in bytes.
  • Size distribution: size of disk procountry allocated for a file on the storage medium, which can always be even a multiple of the cluster size.
  • Allowed data length: the length of the actually written data in the file in bytes. This value is always significantly less than or equal to the initial size.

The SetEndOfFile function sets the file size. Use SetFileValidData to set the length of the applicable data.

If
CreateFileMapping called to create a real file mapping object for hFile. UnmapViewOfFile must be named first to de-display all views, and CloseHandle to close file association elements before you can call SetEndOfFile.
