2000-08-08 Jeff Johnston <jjohnstn@redhat.com> * libc/stdio/snprintf.c (snprintf, _snprintf_r): Fixed code so size of 0 results in nothing being written to string. Also fixed code so that when size is non-zero, there is only a maximum of size - 1 characters written to the array and a nul terminator is appended at the end. * libc/stdio/vsnprintf.c (vsnprintf, _vsnprintf_r): Ditto.
