):Boolean;

Notes

Call this function after calling FileMarkRead when you are done reading a file.

This function is for when you are sharing files among several people at once, or when edit conflicts could occur. An example of when file sharing is needed: if you design wiki that is file system based instead of database driven. Common files are being accessed at once by several people in a wiki, and you would not want files to be overwritten or read at the sime time someone else was writing to the file.

Example

var
  k: word;
begin
  FileMarkRead('filename.ext', k);
  assign(fh, 'filename.ext');
  reset(fh);
  // Some actions
  close(fh);
  FileUnmarkRead('filename.ext', k);
end.
