splint now tried to define a symbol based on the current processor type.

[splint.git] / test / help.expect

Source files are .c, .h and .lcl files.  If there is no suffix,
   Splint will look for <file>.c and <file>.lcl.

Use splint -help <topic or flag name> for more information

Topics:

   annotations (describes source-code annotations)
   comments (describes control comments)
   flags (describes flag categories)
   flags <category> (describes flags in category)
   flags all (short description of all flags)
   flags alpha (list all flags alphabetically)
   flags full (full description of all flags)
   mail (information on mailing lists)
   modes (show mode settings)
   parseerrors (help on handling parser errors)
   prefixcodes (character codes in namespace prefixes)
   references (sources for more information)
   vars (environment variables)
   version (information on compilation, maintainer)

sysdirs --- set directories for system files (default /usr/include). Separate
directories with path separator (colons in Unix, semi-colons in Windows). Flag
settings propagate to files in a system directory. If -sysdirerrors is set, no
errors are reported for files in system directories.
skipansiheaders --- prevent inclusion of header files in a system directory
with names that match standard ANSI headers. The symbolic information in the
standard library is used instead.  Flag in effect only if a library including
the ANSI library is loaded.  The ANSI headers are:
assert, ctype, errno, float, limits, locale, math, setjmp, signal, stdarg,
stddef, stdio, stdlib, strings, string, time, and wchar.
skipposixheaders --- prevent inclusion of header files in a system directory
with names that match standard POSIX headers. The symbolic information in the
posix library is used instead.  The POSIX headers are:
dirent, fcntl, grp, pwd, termios, sys/stat, sys/times, sys/types, sys/utsname,
sys/wait, unistd, and utime.
