DESCRIPTION
|
|
<<vprintf>>, <<vfprintf>>, <<vasprintf>>, <<vsprintf>>, <<vsnprintf>>,
|
|
and <<vasnprintf>> are (respectively) variants of <<printf>>,
|
|
<<fprintf>>, <<asprintf>>, <<sprintf>>, <<snprintf>>, and
|
|
<<asnprintf>>. 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>>.
|
|
|
|
<<_vprintf_r>>, <<_vfprintf_r>>, <<_vasprintf_r>>, <<_vsprintf_r>>,
|
|
<<_vsnprintf_r>>, and <<_vasnprintf_r>> are reentrant versions of the
|
|
above.
|
|
|
|
RETURNS
|
|
The return values are consistent with the corresponding functions.
|
|
|
|
PORTABILITY
|
|
ANSI C requires <<vprintf>>, <<vfprintf>>, <<vsprintf>>, and
|
|
<<vsnprintf>>. The remaining functions are newlib extensions.
|
|
|
|
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
|
|
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
