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 does not return a byte count as specified in C99 on some platforms:
16 HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 9, mingw.
18 This function overwrites memory even when a size argument of 1 is passed on some
23 Portability problems fixed by Gnulib module @code{snprintf-posix}:
26 This function does not support size specifiers as in C99 (@code{hh}, @code{ll},
27 @code{j}, @code{t}, @code{z}) on some platforms:
28 AIX 5.1, HP-UX 11.23, IRIX 6.5, OSF/1 5.1, Solaris 9, Cygwin 1.5.24, mingw, BeOS.
30 printf of @samp{long double} numbers is unsupported on some platforms:
33 printf @code{"%f"}, @code{"%e"}, @code{"%g"} of Infinity and NaN yields an
34 incorrect result on some platforms:
35 AIX 5.2, OSF/1 5.1, Solaris 11 2010-11, mingw.
37 This function does not support the @samp{a} and @samp{A} directives on some
39 glibc-2.3.6, MacOS X 10.5, NetBSD 5.0, OpenBSD 4.0, AIX 5.2, HP-UX 11,
40 IRIX 6.5, OSF/1 5.1, Solaris 11 2010-11, Cygwin 1.5.x, mingw, BeOS.
42 This function does not support the @samp{F} directive on some platforms:
43 NetBSD 3.0, AIX 5.1, HP-UX 11.23, IRIX 6.5, OSF/1 5.1, Solaris 9,
44 Cygwin 1.5.x, mingw, BeOS.
46 This function does not support the @samp{ls} directive on some platforms:
47 OpenBSD 4.0, IRIX 6.5, Solaris 2.6, Cygwin 1.5.x, Haiku.
49 This function does not support precisions in the @samp{ls} directive correctly
53 This function does not support format directives that access arguments in an
54 arbitrary order, such as @code{"%2$s"}, on some platforms:
55 NetBSD 3.0, mingw, BeOS.
57 This function doesn't support the @code{'} flag on some platforms:
58 NetBSD 3.0, Cygwin 1.5.24, mingw.
60 This function behaves incorrectly when a @samp{-} flag and a negative width
61 are specified together, on some platforms:
64 printf @code{"%010f"} of NaN and Infinity yields an incorrect result (padded
65 with zeroes) on some platforms:
66 MacOS X 10.5, FreeBSD 6.0, NetBSD 5.0, AIX 5.2, IRIX 6.5, OSF/1 5.1, Solaris 11 2010-11, Cygwin 1.5.x, mingw.
68 This function does not support precisions larger than 512 or 1024 in integer,
69 floating-point and pointer output on some platforms:
70 Solaris 10/x86, mingw, BeOS.
72 This function mishandles large floating point precisions
73 (for example, formatting 1.0 with @samp{"%.511f"})
77 This function can crash in out-of-memory conditions on some platforms:
78 MacOS X 10.3, FreeBSD 6.0, NetBSD 5.0.
80 This function does not truncate the result as specified in C99 on some platforms:
83 This function does not fully support the @samp{n} directive on some platforms:
86 This function overwrites memory when a size = 1 argument is passed on some
90 This function overwrites memory even when a zero size argument is passed on some
