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>>.
