DESCRIPTION
Function dwarf_vendor_ext() adds a vendor-specific macro information
entry to a DWARF producer instance.
Argument dbg should reference a DWARF producer instance allocated using
dwarf_producer_init(3) or dwarf_producer_init_b(3).
Argument constant specifies a constant value for the macro information
entry.
Argument string point to a NUL-terminated string containing the string
value for the macro information entry.
If argument err is not NULL, it will be used to store error information
in case of an error.
The meaning of the arguments constant and string are not defined by the
DWARF specification, but are instead governed by application and vendor
conventions.

On success, function dwarf_vendor_ext() returns DW_DLV_OK. In case of an
error, function dwarf_vendor_ext() returns DW_DLV_ERROR and sets the
argument err.

[DW_DLE_ARGUMENT] Either arguments dbg or string was NULL.
