.Dd November 9, 2011 .Dt DWARF_FINISH 3 .Os .Sh NAME .Nm dwarf_finish , .Nm dwarf_object_finish .Nd free resources associated with a debug descriptor .Sh LIBRARY .Lb libdwarf .Sh SYNOPSIS n libdwarf.h .Ft int .Fn dwarf_finish "Dwarf_Debug dbg" "Dwarf_Error *err" .Ft int .Fn dwarf_object_finish "Dwarf_Debug dbg" "Dwarf_Error *err" .Sh DESCRIPTION The .Fn dwarf_finish and .Fn dwarf_object_finish functions are used to release the resources associated with a debug descriptor allocated by a prior call to .Xr dwarf_init 3 and .Xr dwarf_object_init 3 respectively.
p Argument .Fa dbg denotes a valid .Vt Dwarf_Debug instance. Argument .Fa err will be used to record error information in case of an error.
p After a call to .Fn dwarf_finish or .Fn dwarf_object_finish , the argument .Fa dbg will be invalid and should not be used further.
p For .Vt Dwarf_Debug descriptors opened using .Xr dwarf_init 3 , the application would need to explicitly release the .Vt Elf instance associated with the descriptor by first retrieving the instance using .Xr dwarf_get_elf 3 and closing it using .Xr elf_end 3 . .Sh RETURN VALUES These functions return .Dv DW_DLV_OK if successful. In case of an error, the functions return .Dv DW_DLV_ERROR and record additional information in argument .Fa err . .Sh EXAMPLES To deallocate a .Vt Dwarf_Debug instance allocated using .Xr dwarf_elf_init 3 use: d -literal -offset indent Dwarf_Debug dbg; Dwarf_Error de; if (dwarf_finish(dbg, &de) != DW_DLV_OK) errx(EXIT_FAILURE, "dwarf_finish: %s", dwarf_errmsg(de)); .Ed
p To deallocate a .Vt Dwarf_Debug instance allocated using .Xr dwarf_object_init 3 use: d -literal -offset indent 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)); .Ed
p To deallocate a .Vt Dwarf_Debug instance allocated using .Xr dwarf_init 3 use: d -literal -offset indent 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); .Ed .Sh SEE ALSO .Xr dwarf_elf_init 3 , .Xr dwarf_get_elf 3 , .Xr dwarf_init 3 , .Xr dwarf_object_init 3 , .Xr elf_end 3
