DWARF_ADD_AT_FLAG(3)       Library Functions Manual       DWARF_ADD_AT_FLAG(3)

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.
