/* This file exports one function
|
|
|
|
char *cplus_demangle (const char *name, int mode)
|
|
|
|
If NAME is a mangled function name produced by GNU C++, then
|
|
a pointer to a malloced string giving a C++ representation
|
|
of the name will be returned; otherwise NULL will be returned.
|
|
It is the caller's responsibility to free the string which
|
|
is returned.
|
|
|
|
If MODE > 0, then ANSI qualifiers such as `const' and `void' are output.
|
|
Otherwise they are not.
|
|
If MODE >= 0, parameters are emitted; otherwise not.
|
|
|
|
For example,
|
|
|
|
cplus_demangle ("foo__1Ai", 0) => "A::foo(int)"
|
|
cplus_demangle ("foo__1Ai", 1) => "A::foo(int)"
|
|
cplus_demangle ("foo__1Ai", -1) => "A::foo"
|
|
|
|
cplus_demangle ("foo__1Afe", 0) => "A::foo(float,...)"
|
|
cplus_demangle ("foo__1Afe", 1) => "A::foo(float,...)"
|
|
cplus_demangle ("foo__1Afe", -1) => "A::foo"
|
|
|
|
This file imports xmalloc and xrealloc, which are like malloc and
|
|
realloc except that they generate a fatal error if there is no
|
|
available memory. */
