extern int x1f4_lock_lxcast (const void *lxcast, int to, int from, const struct x1f4_linetext_type **convertor_store);
x1f4_lock_lxcast function constructs implicit convertors to and from
the object data type. If one of
from matches the
‘object’ type id as stored by the
lxcast object library
x1f4_lock_lxcast will construct a data implicit convertor from
from data type to the
to data type and store its address at
The function together with an object library object may be used an implicit data type convertor constructor for the various interfaces that use such artefacts.
See Application Defined Implicit Conversions.
See Function Converters Set Definition.
The constructed convertor is recorded with the
library object and destroyed with the library object.
The function returns
0 for success,
1 for the inability to
construct a converter, one of the defined error codes for failure.
