Description Jakub Jelinek 2011-03-03 08:44:01 UTC

"The  trailing null byte won't be added to str, if the string is truncated." claim in man 3 snprintf (seen on F14 up to latest f16 man pages in mock buildroot)
is wrong, it is not what glibc snprintf implements nor what man 3p snprintf
says.  snprintf terminates the string with a null byte always, unless the size is zero (then it of course doesn't write anything).

Thanks, resolves in man-pages-3.32-11.fc16
changed to 
The trailing null byte is added to str, unless size is zero.
