7 Gnulib module: snprintf or snprintf-posix
9 Portability problems fixed by either Gnulib module @code{snprintf} or @code{snprintf-posix}:
12 This function is missing on some platforms:
13 IRIX 5.3, OSF/1 4.0, Solaris 2.5.1.
15 This function overwrites memory even when a size argument of 1 is passed on some
20 Portability problems fixed by Gnulib module @code{snprintf-posix}:
23 This function does not support size specifiers as in C99 (@code{hh}, @code{ll},
24 @code{j}, @code{t}, @code{z}) on some platforms:
25 AIX 5.1, HP-UX 11.23, IRIX 6.5, OSF/1 5.1, Solaris 9, Cygwin 2006, mingw, BeOS.
27 printf of @samp{long double} numbers is unsupported on some platforms:
30 printf @code{"%f"}, @code{"%e"}, @code{"%g"} of Infinity and NaN yields an
31 incorrect result on some platforms:
32 AIX 5.2, OSF/1 5.1, Solaris 10, mingw.
34 This function does not support the @samp{a} and @samp{A} directives on some
36 glibc-2.3.6, MacOS X 10.3, NetBSD 3.0, OpenBSD 4.0, AIX 5.2, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 10, Cygwin, mingw, BeOS.
38 This function does not support the @samp{F} directive on some platforms:
39 NetBSD 3.0, AIX 5.1, HP-UX 11.23, IRIX 6.5, OSF/1 5.1, Solaris 9, Cygwin, mingw, BeOS.
41 This function does not support format directives that access arguments in an
42 arbitrary order, such as @code{"%2$s"}, on some platforms:
43 NetBSD 3.0, mingw, BeOS.
45 This function doesn't support the @code{'} flag on some platforms:
46 NetBSD 3.0, Cygwin 2006, mingw.
48 This function behaves incorrectly when a @samp{-} flag and a negative width
49 are specified together, on some platforms:
52 printf @code{"%010f"} of NaN and Infinity yields an incorrect result (padded
53 with zeroes) on some platforms:
54 MacOS X 10.3, FreeBSD 6.0, NetBSD 3.0, AIX 5.2, IRIX 6.5, OSF/1 5.1, Solaris 10, Cygwin 2007, mingw.
56 This function does not support precisions larger than 512 or 1024 in integer,
57 floating-point and pointer output on some platforms:
60 This function can crash in out-of-memory conditions on some platforms:
61 MacOS X 10.3, FreeBSD 6.0, NetBSD 3.0.
63 This function does not truncate the result as specified in C99 on some platforms:
66 This function does not return a byte count as specified in C99 on some platforms:
67 HP-UX 11, IRIX 6.5, OSF/1 5.1, mingw.
69 This function does not fully support the @samp{n} directive on some platforms:
72 This function overwrites memory when a size = 1 argument is passed on some
76 This function overwrites memory even when a zero size argument is passed on some
