ELFTC_DEMANGLE(3) FreeBSD Library Functions Manual ELFTC_DEMANGLE(3) NAME elftc_demangle - demangle a C++ name LIBRARY library "libelftc" SYNOPSIS #include <libelftc.h> int elftc_demangle(const char *encodedname, char *buffer, size_t bufsize, unsigned int flags); DESCRIPTION Function elftc_demangle() decodes a symbol name encoded according to the type encoding rules for the C++ language and returns a string denoting an equivalent C++ prototype. Argument encodedname specifies the encoded symbol name. Argument buffer denotes a programmer-specified area to place the prototype string in. Argument bufsize specifies the size of the programmer-specified area. Argument flags specifies the encoding style in use for argument encodedname. Supported encoding styles are: ELFTC_DEM_ARM The encoding style used by compilers adhering to the conventions of the C++ Annotated Reference Manual. ELFTC_DEM_GNU2 The encoding style by GNU C++ version 2. ELFTC_DEM_GNU3 The encoding style by GNU C++ version 3 and later. Argument flags may be zero, in which case the function will attempt to guess the encoding scheme from the contents of encodedname. RETURN VALUES Function elftc_demangle() returns 0 on success. In case of an error it returns -1 and sets the errno variable. EXAMPLES To decode a name that uses an unknown encoding style use: char buffer[1024]; const char *funcname; funcname = ...; /* points to string to be demangled */ if (elftc_demangle(funcname, buffer, sizeof(buffer), 0) == 0) printf("Demangled name: %\n", buffer); else perror("Cannot demangle %s", funcname); ERRORS Function elftc_demangle() may fail with the following errors: [EINVAL] Argument encodedname was not a valid encoded name. [ENAMETOOLONG] The output buffer specified by arguments buffer and bufsize was too small to hold the decoded function prototype.
