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>>. */ #include <_ansi.h> #include <reent.h> #include <stdio.h> #ifdef _HAVE_STDC #include <stdarg.h> #else #include <varargs.h> #endif #include "local.h" #ifndef _REENT_ONLY int _DEFUN(viprintf, (fmt, ap), _CONST char *fmt _AND va_list ap) { _REENT_SMALL_CHECK_INIT (_REENT); return _vfiprintf_r (_REENT, _stdout_r (_REENT), fmt, ap); } #endif /* !_REENT_ONLY */ int _DEFUN(_viprintf_r, (ptr, fmt, ap), struct _reent *ptr _AND _CONST char *fmt _AND va_list ap) { _REENT_SMALL_CHECK_INIT (ptr); return _vfiprintf_r (ptr, _stdout_r (ptr), fmt, ap); }
