I have a piece of code to download a file from server. However, due to server constraint, I can not put .exe file at server. So I rename my XXX.exe file to XXX.alt(just a random extension) and put it on server.
Now my code can download XXX.alt, but how can I change the file name from XXX.alt back to XXX.exe when in QT environment?
Just use rename function from 'stdio.h'.
char oldname ="XXX.alt"; char newname ="XXX.exe"; result= rename( oldname , newname ); if ( result == 0 ) puts ( "File successfully renamed" ); else perror( "Error renaming file" );
