@kindex cxxfilt
-The C++ and Java languages provides function overloading, which means
-that you can write many functions with the same name (providing each

+The C++ and Java languages provide function overloading, which means
+that you can write many functions with the same name, providing that
+each function takes parameters of different types. In order to be
+able to distinguish these similarly named functions C++ and Java
+encode them into a low-level assembler name which uniquely identifies
+each different version. This process is known as @dfn{mangling}. The
+@command{c++filt}
+@footnote{MS-DOS does not allow @kbd{+} characters in file names, so on
+MS-DOS this program is named @command{CXXFILT}.}
program does the inverse mapping: it decodes (@dfn{demangles}) low-level
-names into user-level names so that the linker can keep these overloaded
-functions from clashing.
+names into user-level names so that they can be read.
Every alphanumeric word (consisting of letters, digits, underscores,
-dollars, or periods) seen in the input is a potential label. If the
-label decodes into a C++ name, the C++ name replaces the low-level
-name in the output.
+dollars, or periods) seen in the input is a potential mangled name.
+If the name decodes into a C++ name, the C++ name replaces the
+low-level name in the output, otherwise the original word is output.
+In this way you can pass an entire assembler source file, containing
+mangled names, through @command{c++filt} and see the same source file
+containing demangled names.
-You can use @command{c++filt} to decipher individual symbols:
+You can also use @command{c++filt} to decipher individual symbols by
+passing them on the command line:
@example
c++filt @var{symbol}
@end example
If no @var{symbol} arguments are given, @command{c++filt} reads symbol
-names from the standard input and writes the demangled names to the
-standard output. All results are printed on the standard output.
+names from the standard input instead. All the results are printed on
+the standard output. The difference between reading names from the
+command line versus reading names from the standard input is that
+command line arguments are expected to be just mangled names and no
+checking is performed to seperate them from surrounding text. Thus
+for example:
+
+@smallexample
+c++filt -n _Z1fv
+@end smallexample
+
+will work and demangle the name to ``f()'' whereas:
+
+@smallexample
+c++filt -n _Z1fv,
+@end smallexample
+
+will not work. (Note the extra comma at the end of the mangled
+name which makes it invalid). This command however will work:
+
+@smallexample
+echo _Z1fv, | c++filt -n
+@end smallexample
+
+and will display ``f(),'' ie the demangled name followed by a
+trailing comma. This behaviour is because when the names are read
+from the standard input it is expected that they might be part of an
+assembler source file where there might be extra, extraneous
+characters trailing after a mangled name. eg:
+
+@smallexample
+ .type _Z1fv, @@function
+@end smallexample
@c man end
When demangling the name of a function, do not display the types of
the function's parameters.
+@item -t
+@itemx --types
+Attempt to demangle types as well as function names. This is disabled
+by default since mangled types are normally only used internally in
+the compiler, and they can be confused with non-mangled names. eg
+a function called ``a'' treated as a mangled type name would be
+demangled to ``signed char''.
+
+@item -i
+@itemx --no-verbose
+Do not include implementation details (if any) in the demangled
+output.

+@command{dlltool} is used to create the files needed to create dynamic

+
+The export table is generated by this program by reading in a
