25 | If NAME is a mangled function name produced by GNU C++, then |
26 | a pointer to a malloced string giving a C++ representation | |
27 | of the name will be returned; otherwise NULL will be returned. | |
28 | It is the caller's responsibility to free the string which | |
29 | is returned. | |
30 | ||
31 | If MODE > 0, then ANSI qualifiers such as `const' and `void' are output. | |
32 | Otherwise they are not. | |
33 | If MODE >= 0, parameters are emitted; otherwise not. | |
34 | ||
35 | For example, | |
36 | ||
37 | cplus_demangle ("foo__1Ai", 0) => "A::foo(int)" | |
38 | cplus_demangle ("foo__1Ai", 1) => "A::foo(int)" | |
39 | cplus_demangle ("foo__1Ai", -1) => "A::foo" | |
40 | ||
41 | cplus_demangle ("foo__1Afe", 0) => "A::foo(float,...)" | |
42 | cplus_demangle ("foo__1Afe", 1) => "A::foo(float,...)" | |
43 | cplus_demangle ("foo__1Afe", -1) => "A::foo" | |

45 | This file imports xmalloc and xrealloc, which are like malloc and | |
