+
+SYNOPSIS
+
+ static int
+ demangle_signature (string *declp, const char **mangled,
+ struct work_stuff *work);
+
+DESCRIPTION
+
+ Consume and demangle the signature portion of the mangled name.
+
+ DECLP is the string where demangled output is being built. At
+ entry it contains the demangled root name from the mangled name
+ prefix. I.E. either a demangled operator name or the root function
+ name. In some special cases, it may contain nothing.
+
+ *MANGLED points to the current unconsumed location in the mangled
+ name. As tokens are consumed and demangling is performed, the
+ pointer is updated to continuously point at the next token to
+ be consumed.
+
+ Demangling GNU style mangled names is nasty because there is no
+ explicit token that marks the start of the outermost function
+ argument list.
