Function
dwarf_add_AT_string() creates an attribute
descriptor belonging to the ‘string’ class and attaches it to
the debugging information entry referenced by argument
die. The created attribute descriptor will
have DWARF form
DW_FORM_strp
.
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 created attribute descriptor.
Argument
str should hold a pointer to a
NUL-terminated string which will become the value of the created attribute
descriptor.
If argument
err is not NULL, it will be used to
store error information in case of an error.
On success, function
dwarf_add_AT_string() returns
the created attribute descriptor. In case of an error, function
dwarf_add_AT_string() returns
DW_DLV_BADADDR
and sets the argument
err.
