[sr-dev] Problem with pv_get_strval()

[Iñaki Baz Castillo]

Hi, from an external library function I get a pointer to a \0
terminated string, and I want to get such string as PV value. In the
module code I do:

------------------------------
static str *external_lib_reply;


[...]


static int child_init(int rank)
{
  external_lib_reply = pkg_malloc(sizeof(str*));
}


[...]


static int pv_get_external_lib_reply(struct sip_msg *msg, pv_param_t
*param, pv_value_t *res)
{
  if (! *external_lib_reply->s) {
    LM_ERR("pv 'external_lib_reply' doesn't have value\n");
    return pv_get_null(msg, param, res);
  }
  else {
    return pv_get_strval(msg, param, res, external_lib_reply);
  }
}


[...]


// Exported module function:
static int w_external_lib_do_request(struct sip_msg* _msg, char* _s1,
char* _s2) {

  // Here I get a \0 terminated pointer to char:
  char *replied_string;
  [...]
  replied_string = [...];

  // Then I want to assign its value to the PV:
  // line 209:
  *external_lib_reply->s = replied_string;
  // line 210:
  *external_lib_reply->len = strlen(replied_string);

  [...]
}
-----------------------------


I get compilation error in this last part:

  209: warning: assignment makes integer from pointer without a cast
  210: error: invalid type argument of ‘unary *’ (have ‘int’)


I don't understand the reason of the warning neither the reason of the
error. Any help please?

Thanks a lot.
