Function dwarf_get_pubtypes() retrieves descriptors for all the user-defined types associated with the DWARF debug context specified by argument dbg. The argument types should point to a location that will be set to a pointer to an array of Dwarf_Type descriptors. The argument ntypes should point to a location that will be set to the number of descriptors returned.
Function dwarf_pubtype_cu_offset() returns the offset, relative to the “.debug_info” section, of the compilation unit that contains the debugging information entry associated with the argument type. Argument cu_offset should point to a location that will hold the returned offset.
Function dwarf_pubtype_die_offset() retrieves the offset, relative to the “.debug_info” section, of the debugging information entry associated with the argument type, and stores it into the location pointed to by the argument die_offset.
Function dwarf_pubtype_name_offsets() retrieves the name and offsets for the debugging information entry for argument type. Argument name should point to a location which will be set to a pointer to a NUL-terminated string containing the name of the associated debugging information entry. Argument die_offset should point to a location which will be set to the offset, relative to the “.debug_info” section, of the associated debugging information entry. Argument cu_die_offset should point to a location which will be set to the offset, relative to the “.debug_info” section, of the first debugging information entry in the compilation unit associated with argument type.
Function dwarf_pubtypename() sets the location pointed to by argument name to a pointer to a NUL-terminated string holding the name of the debugging information entry associated with the argument type.
The memory area used for the string returned in the name argument to functions dwarf_pubtype_name_offsets() and dwarf_pubtypename() is owned by the DWARF Access Library (libdwarf, -ldwarf). Portable code should indicate that the memory area can be freed using the dwarf_dealloc(3) function.
