Function
dwarf_vendor_ext() adds a vendor-specific
macro information entry to a DWARF producer instance.

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.

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.
