DWARF_DIE_LINK(3)					   BSD Library Functions Manual 					 DWARF_DIE_LINK(3)

NAME

     dwarf_die_link -- link a debugging information entry

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     Dwarf_P_Die
     dwarf_die_link(Dwarf_P_Die die, Dwarf_P_Die parent, Dwarf_P_Die child, Dwarf_P_Die left, Dwarf_P_Die right, Dwarf_Error *err);

DESCRIPTION

     Function dwarf_die_link() links debugging information entries together.

     Argument die should specify the debugging information entry to be updated.

     Argument parent specifies the new parent link for the debugging information entry.

     Argument child specifies the new first child link for the debugging information entry.

     Argument left specifies the new left sibling link for the debugging information entry.

     Argument right specifies the new right sibling link for the debugging information entry.

     Only one of arguments parent, child, left and right is allowed to be non-NULL.  Existing links to parent, child, left or right debugging
     information entries, if any, will be unlinked before the specified link is established.

     If argument err is not NULL, it will be used to store error information in case of an error.

RETURN VALUES

     On success, function dwarf_die_link() returns the debugging information entry provided in argument die.  In case of an error, function
     dwarf_die_link() returns DW_DLV_BADADDR and sets the argument err.

ERRORS

     The function dwarf_die_link() can fail with:

     [DW_DLE_ARGUMENT]	Argument die was NULL.

     [DW_DLE_ARGUMENT]	More than one of the arguments parent, child, left and right were non-NULL.

NAME

     dwarf_add_AT_reference -- create and attach an attribute that references another DIE

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     Dwarf_P_Attribute
     dwarf_add_AT_reference(Dwarf_P_Debug dbg, Dwarf_P_Die die, Dwarf_Half attr, Dwarf_P_Die ref_die, Dwarf_Error *err);

DESCRIPTION

     Function dwarf_add_AT_reference() creates an attribute descriptor that references another debugging information entry in the same compilation
     unit.  The attribute will be of DWARF form DW_FORM_ref4 or DW_FORM_ref8 depending on the target address size, and will contain the section-
     relative offset of the referenced debugging information entry as its value.

     Argument dbg should reference a DWARF producer instance allocated using dwarf_producer_init(3) or dwarf_producer_init_b(3).

     Argument die should reference a debugging information entry allocated using dwarf_new_die(3).

     Argument attr should specify the attribute code of the created attribute descriptor.

     Argument ref_die should hold the debugging information entry descriptor that the attribute should refer to.

     If argument err is not NULL, it will be used to store error information in case of an error.

RETURN VALUES

     On success, function dwarf_add_AT_reference() returns the created attribute descriptor.  In case of an error, function
     dwarf_add_AT_reference() returns DW_DLV_BADADDR and sets the argument err.

ERRORS

     Function dwarf_add_AT_reference() can fail with:

     [DW_DLE_ARGUMENT]	One of the arguments dbg, die or ref_die was NULL.

     [DW_DLE_MEMORY]	An out of memory condition was encountered during the execution of the function.
