Well, I think I've already got it by copying some functions of "rr" module:
int my_function(struct sip_msg *msg, char *key, char *foo)
{
str s;
if (pv_printf_s(msg, (pv_elem_t*)key, &s)<0) {
LM_ERR("failed to print the format\n");
return -1;
}
# do something with s.s
}
static int it_list_fixup(void** param, int param_no)
{
pv_elem_t *model;
str s;
if(*param)
{
s.s = (char*)(*param); s.len = strlen(s.s);
if(pv_parse_format(&s, &model)<0)
{
LM_ERR("wrong format[%s]\n",(char*)(*param));
return E_UNSPEC;
}
*param = (void*)model;
}
return 0;
}
