DESCRIPTION
<<viprintf>>, <<vfiprintf>>, <<vasiprintf>>, <<vsiprintf>>,
<<vsniprintf>>, and <<vasniprintf>> are (respectively) variants of
<<iprintf>>, <<fiprintf>>, <<asiprintf>>, <<siprintf>>, <<sniprintf>>,
and <<asniprintf>>.  They differ only in allowing their caller to pass
the variable argument list as a <<va_list>> object (initialized by
<<va_start>>) rather than directly accepting a variable number of
arguments.  The caller is responsible for calling <<va_end>>.
 
<<_viprintf_r>>, <<_vfiprintf_r>>, <<_vasiprintf_r>>,
<<_vsiprintf_r>>, <<_vsniprintf_r>>, and <<_vasniprintf_r>> are
reentrant versions of the above.
 
RETURNS
The return values are consistent with the corresponding functions:
 
PORTABILITY
All of these functions are newlib extensions.
 
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
