creazione di file temporaneo intuibile, penso. apri un file che gia' c'e'

http://www.gnu.org/manual/glibc-2.2.3/html_node/libc_285.html

Function: char * tmpnam (char *result) 

Warning: Between the time the pathname is constructed and the file is
created another process might have created a file with the same name using
tmpnam, leading to a possible security hole. The implementation generates
names which can hardly be predicted, but when opening the file you should
use the O_EXCL flag. Using tmpfile or mkstemp is a safe way to avoid this
problem.

probabilmente su questo prog problemi di sicurezza non ne crea, comunque e'
una funzione sconsigliata.
