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);

remove the '*' from the front of the lines.

Cheers, Daniel

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.
