@node wprintf @section @code{wprintf} @findex wprintf POSIX specification:@* @url{https://pubs.opengroup.org/onlinepubs/9699919799/functions/wprintf.html} Gnulib module: --- Portability problems fixed by Gnulib: @itemize @end itemize Portability problems not fixed by Gnulib: @itemize @item This function is missing on some platforms: NetBSD 3.0, OpenBSD 3.8, Minix 3.1.8, HP-UX 11.00, IRIX 6.5. @item This function exists, but does not support wide arguments on some platforms: Cygwin 1.5.x. @item On Windows and 32-bit AIX platforms, @code{wchar_t} is a 16-bit type and therefore cannot accommodate all Unicode characters. @item This function does not support size specifiers as in C23 (@code{w8}, @code{w16}, @code{w32}, @code{w64}, @code{wf8}, @code{wf16}, @code{wf32}, @code{wf64}) on some platforms: glibc, musl libc, macOS 12.5, FreeBSD 13.2, NetBSD 9.0, OpenBSD 7.2, AIX 7.2, HP-UX 11, Solaris 11.4, Cygwin 2.9.0, mingw, MSVC 14. @item This function does not support the @samp{b} directive, required by ISO C23, on some platforms: glibc 2.34, musl libc, macOS 12.5, FreeBSD 13.2, NetBSD 9.0, OpenBSD 7.2, AIX 7.2, HP-UX 11, Solaris 11.4, Cygwin 2.9.0, mingw, MSVC 14. @item printf @code{"%#.0x"} or @code{"%#.0X"} with a zero argument yields an incorrect result (non-empty) on some platforms: Mac OS X 10.6. @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 In the C or POSIX locales, the @code{%c} and @code{%s} conversions may fail on some platforms: glibc 2.35. @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
