Is there a way to replace any keyword in a text file using POSIX calls, without re creating the file.. If yes Please tell me how to do it..

Thanks in advance..

If the text and the replacement are the same size then you can open it with mode r+, seek, and then write. If their sizes are different then there is no way to replace without recreating.
