ramona,

that worked fine.  now i have in mod_init of shv_test module:

    /* Shared variable test */
    name.s = "$shv(enum_domains)";
    name.len = strlen(name.s);
    if (pv_parse_spec(&name, &spec) == NULL) {
	LM_ERR("invalid shared variable specification\n");
	return -1;
    }
    memset(&value, 0, sizeof(pv_value_t));
    value.rs.s = "e164.arpa.";
    value.rs.len = strlen(value.rs.s);
    value.flags = PV_VAL_STR;
    spec.setf(NULL, &spec.pvp, EQ_T, &value);

and shared variable $shv(enum_domains) gets correctly assigned value
"e164.arpa.", if and only if i have:

loadmodule "cfgutils.so"
loadmodule "shv_test.so"
...
modparam("cfgutils", "shvset", "enum_domains=s:foo")

that is, i create shared variable ""enum_domains" by cfgutils module.

however, if i don't define the above cfgutils shvset module parameter, i
get error message:

Aug 26 17:09:18 localhost /usr/sbin/kamailio[22934]: ERROR:core:pv_parse_spec: error searching pvar "shv" 
Aug 26 17:09:18 localhost /usr/sbin/kamailio[22934]: ERROR:core:pv_parse_spec: wrong char [e/101] in [$shv(enum_domains)] at [5 (5)]

Aug 26 17:09:18 localhost /usr/sbin/kamailio[22934]: ERROR:core:init_mod: failed to initialize module shv_test

my next question is, how can i create a new shared variable in shv_test
module without a need to do that by cfgutils module?  i have searched
core/pvar.h, but have not found a pv create function.
