DEMANGLE(3EXT) Extended Library Functions DEMANGLE(3EXT)

NAME

demangle, cplus_demangle - decode a C++ encoded symbol name

SYNOPSIS

cc [ flag ... ] file[ library ... ] -ldemangle

#include <demangle.h>


int cplus_demangle(const char *symbol, char *prototype, size_t size);

DESCRIPTION

The cplus_demangle() function decodes (demangles) a C++ linker symbol
name (mangled name) into a (partial) C++ prototype, if possible.
C++ mangled names may not have enough information to form a complete
prototype.


The symbol string argument points to the input mangled name.


The prototype argument points to a user-specified output string
buffer, of size bytes.


The cplus_demangle() function operates on mangled names generated by
SPARCompilers C++ 3.0.1, 4.0.1, 4.1 and 4.2.


The cplus_demangle() function improves and replaces the demangle()
function.


Refer to the CC.1, dem.1, and c++filt.1 manual pages in the
/opt/SUNWspro/man/man1 directory. These pages are only available
with the SPROcc package.

RETURN VALUES

The cplus_demangle() function returns the following values:

0
The symbol argument is a valid mangled name and
prototype contains a (partial) prototype for the
symbol.


DEMANGLE_ENAME
The symbol argument is not a valid mangled name
and the content of prototype is a copy of the
symbol.


DEMANGLE_ESPACE
The prototype output buffer is too small to
contain the prototype (or the symbol), and the
content of prototype is undefined.
