@node vdprintf @section @code{vdprintf} @findex vdprintf POSIX specification:@* @url{http://www.opengroup.org/onlinepubs/9699919799/functions/vdprintf.html} Gnulib module: vdprintf or vdprintf-posix Portability problems fixed by either Gnulib module @code{vdprintf} or @code{vdprintf-posix}: @itemize @item This function is missing on some platforms: Mac OS X 10.5, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 11.3, Cygwin 1.5.x, mingw, MSVC 14, Interix 3.5. @end itemize Portability problems fixed by Gnulib module @code{vdprintf-posix}: @itemize @item This function does not support size specifiers as in C99 (@code{hh}, @code{ll}, @code{j}, @code{t}, @code{z}) on some platforms: BeOS. @item printf of @samp{long double} numbers is unsupported on some platforms: BeOS. @item printf @code{"%f"}, @code{"%e"}, @code{"%g"} of Infinity and NaN yields an incorrect result on some platforms: Solaris 11.4. @item This function does not support the @samp{a} and @samp{A} directives on some platforms: glibc-2.3.6, BeOS. @item This function does not support the @samp{F} directive on some platforms: BeOS. @item This function does not support format directives that access arguments in an arbitrary order, such as @code{"%2$s"}, on some platforms: BeOS. @item printf @code{"%010f"} of NaN and Infinity yields an incorrect result (padded with zeroes, or wrong capitalization) on some platforms: Solaris 11.4. @item This function does not support precisions larger than 512 or 1024 in integer, floating-point and pointer output on some platforms: AIX 7.1, BeOS. @end itemize Portability problems not fixed by Gnulib: @itemize @item The @code{%m} directive is not portable, use @code{%s} mapped to an argument of @code{strerror(errno)} (or a version of @code{strerror_r}) instead. @item Formatting noncanonical @samp{long double} numbers produces nonmeaningful results on some platforms: glibc and others, on x86, x86_64, IA-64 CPUs. @item When formatting an integer with grouping flag, this function inserts thousands separators even in the "C" locale on some platforms: NetBSD 5.1. @item On some platforms, this function does not set @code{errno} or the stream error indicator on attempts to write to a read-only stream: Cygwin 1.7.9. @end itemize
