DWARF_FINISH(3) 					   BSD Library Functions Manual 					   DWARF_FINISH(3)

NAME
dwarf_finish, dwarf_object_finish -- free resources associated with a debug descriptor
LIBRARY
DWARF Access Library (libdwarf, -ldwarf)
SYNOPSIS
#include <libdwarf.h> int dwarf_finish(Dwarf_Debug dbg, Dwarf_Error *err); int dwarf_object_finish(Dwarf_Debug dbg, Dwarf_Error *err);
DESCRIPTION
The dwarf_finish() and dwarf_object_finish() functions are used to release the resources associated with a debug descriptor allocated by a prior call to dwarf_init(3) and dwarf_object_init(3) respectively. Argument dbg denotes a valid Dwarf_Debug instance. Argument err will be used to record error information in case of an error. After a call to dwarf_finish() or dwarf_object_finish(), the argument dbg will be invalid and should not be used further. For Dwarf_Debug descriptors opened using dwarf_init(3), the application would need to explicitly release the Elf instance associated with the descriptor by first retrieving the instance using dwarf_get_elf(3) and closing it using elf_end(3).
RETURN VALUES
These functions return DW_DLV_OK if successful. In case of an error, the functions return DW_DLV_ERROR and record additional information in argument err.
EXAMPLES
To deallocate a Dwarf_Debug instance allocated using dwarf_elf_init(3) use: Dwarf_Debug dbg; Dwarf_Error de; if (dwarf_finish(dbg, &de) != DW_DLV_OK) errx(EXIT_FAILURE, "dwarf_finish: %s", dwarf_errmsg(de)); To deallocate a Dwarf_Debug instance allocated using dwarf_object_init(3) use: Dwarf_Debug dbg; Dwarf_Error de; if (dwarf_object_finish(dbg, &de) != DW_DLV_OK) errx(EXIT_FAILURE, "dwarf_object_finish: %s", dwarf_errmsg(de)); To deallocate a Dwarf_Debug instance allocated using dwarf_init(3) use: Dwarf_Debug dbg; Dward_Error de; Elf *e; if (dwarf_get_elf(dbg, &e, &de) != DW_DLV_OK) errx(EXIT_FAILURE, "dwarf_get_elf: %s", dwarf_errmsg(&de)); if (dwarf_finish(dbg, &de) != DW_DLV_OK) errx(EXIT_FAILURE, "dwarf_finish: %s", dwarf_errmsg(de)); (void) elf_end(e);
