                          const char *<[fmt]>, va_list <[list]>);

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>>.
