Function
dwarf_add_AT_comp_dir() creates a
DW_AT_comp_dir
attribute descriptor and
attaches it to the debugging information entry referenced by argument
die. The created attribute will have DWARF
form
DW_FORM_strp
.
Argument
die should reference a debugging
information entry allocated using
dwarf_new_die(3).
Argument
dir should point to a NUL-terminated
string which will become the value of the created attribute.
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_comp_dir()
returns the created attribute descriptor. In case of an error, function
dwarf_add_AT_comp_dir() returns
DW_DLV_BADADDR
and sets the argument
err.
