NAME
dwarf_add_AT_flag - create and attach a flag attribute
LIBRARY
DWARF Access Library (libdwarf, -ldwarf)
SYNOPSIS
#include <libdwarf.h>
Dwarf_P_Attribute
dwarf_add_AT_flag(Dwarf_P_Debug dbg, Dwarf_P_Die die, Dwarf_Half attr,
Dwarf_Small flag, Dwarf_Error *err);
DESCRIPTION
Function dwarf_add_AT_flag() creates an attribute descriptor belonging to
the `flag' class, and attaches it to the debugging information entry
referenced by argument die. The created attribute descriptor will have
DWARF form DW_FORM_flag.
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 for the new attribute
descriptor.
Argument flag should specify the value of the new attribute descriptor.
A zero value is treated as `false' and a non-zero value as `true'.
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_flag() returns the created attribute
descriptor. In case of an error, function dwarf_add_AT_flag() returns
DW_DLV_BADADDR and sets the argument err.
ERRORS
Function dwarf_add_AT_flag() can fail with:
[DW_DLE_ARGUMENT] Either of the arguments dbg or die was NULL.
[DW_DLE_MEMORY] An out of memory condition was encountered during the
execution of the function.
