Further information
1. If a native function needs to use the reference to an object after its termination, it must tell the system that the corresponding object must be preserved even if it is no longer used in the model: this is the role of this function. When the reference becomes useless for the native code, it must be released by a call to delref. The parameter
type can be
XPRM_TYP_MPVAR,
XPRM_TYP_LINCTR,
XPRM_STR_ARR,
XPRM_STR_LIST,
XPRM_STR_SET or the type code of an external type.
2. If the third argument is
NULL, this function returns the reference to a newly created object.
