5 POSIX specification:@* @url{http://www.opengroup.org/onlinepubs/9699919799/functions/strstr.html}
7 Gnulib module: strstr or strstr-simple
9 Portability problems fixed by either Gnulib module @code{strstr-simple}
13 This function can trigger memchr bugs on some platforms:
16 This function can trigger false positives for long periodic needles on
18 glibc 2.12, Cygwin 1.7.7.
21 Portability problems fixed by Gnulib @code{strstr}:
24 This function has quadratic instead of linear worst-case complexity on some
26 glibc 2.8, Mac OS X 10.5, FreeBSD 6.2, NetBSD 5.0, OpenBSD 4.0, AIX
27 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 11 2011-11, Cygwin 1.5.x, mingw, MSVC 9.
30 Portability problems not fixed by Gnulib:
33 This function cannot work correctly on character strings in most multibyte
34 locales. Gnulib provides an alternative function @code{mbsstr} that works
35 on character strings in all locales.
