The API documentation says that the message is removed of the incoming queue and hence if we call dbus_connection_borrow_message(), it should return NULL. However thats not the case. Any help. Have I misinterpreted the documentation by any chance. The below test code demonstrates the issue. ---- client code --- int main() {         DBusConnection* connection;         DBusError error;         DBusMessage* msg;         DBusMessage* borrow_message;         DBusMessage* reply = NULL;         dbus_int32_t no = 5;         char error_name[40];         char error_msg[40];                 dbus_error_init(&error);                 connection = dbus_bus_get(DBUS_BUS_SESSION, &error);             msg = dbus_message_new_method_call("Test.Method.Call", "/Test/Method/Object", "test.Method.Call", "dbus_connection_borrow_message0");                reply = dbus_connection_send_with_reply_and_block(connection, msg, 10000, &error);                dbus_message_get_args(reply, &error, DBUS_TYPE_INT32, &no, DBUS_TYPE_INVALID);                borrow_message =  dbus_connection_borrow_message (connection )   ;            if(borrow_message)           printf("Error\n");             return 0; }   ---------- end client code ---- ----- Server code ---- #include<stdio.h>  #include "test-utils.h" #include<string.h> #include<ctype.h> #include<unistd.h>  // sleep function is defined in this header file #define TEST_BUS_NAME_TEMP "Test.Method.Call"     void called_dbus_connection_borrow_message0(DBusMessage* msg,DBusConnection* connection)     {     DBusMessage* reply;        dbus_int32_t arg;     dbus_int32_t return_value = 9090;     reply = dbus_message_new_method_return(msg);         dbus_message_append_args(reply, DBUS_TYPE_INT32, &return_value, DBUS_TYPE_INVALID);     dbus_connection_send(connection, reply, NULL);     dbus_connection_flush(connection);     } void called_dbus_connection_pop_message0(DBusMessage* msg,DBusConnection* connection)     {     DBusMessage* reply;        dbus_int32_t arg;     //dbus_int32_t return_value = 9090;     reply = dbus_message_new_method_return(msg);         //dbus_message_append_args(reply, DBUS_TYPE_INT32, &return_value, DBUS_TYPE_INVALID);     dbus_connection_send(connection, reply, NULL);     dbus_connection_flush(connection);     } int main(int argc, char* argv[]) {     DBusError error;     DBusError error1;     DBusConnection* connection;     DBusMessage* msg;     DBusObjectPathVTable vtable;           dbus_error_init(&error);     dbus_error_init(&error1);     fprintf(stdout, "Starting Method"); //    getchar();         connection = dbus_bus_get(DBUS_BUS_SESSION, &error);         if(dbus_error_is_set(&error))     {         fprintf(stdout, "Error Occured :: %s", error.name); //        getchar();         return 1;     }             if(dbus_connection_register_object_path (connection, "/Test/Method/Object", &vtable, NULL))     {         fprintf(stdout, "Object Path registered."); //        getchar();     }     else     {         fprintf(stdout, "Object Path not able to register."); //        getchar();         return 1;     }       if(dbus_bus_request_name (connection, TEST_BUS_NAME_TEMP, DBUS_NAME_FLAG_ALLOW_REPLACEMENT, &error1) == -1)     {         fprintf(stdout, "Not able to request name."); //        getchar();     }     else     {         fprintf(stdout, "Name Request Successful"); //        getchar();     }         while(TRUE)     {            dbus_connection_read_write(connection, 0);                 msg = dbus_connection_pop_message(connection);                     if(msg == NULL)         {             sleep(1);             continue;         }                      fprintf(stdout, "Message Detected");                 if(DBUS_MESSAGE_TYPE_SIGNAL == dbus_message_get_type(msg))         {             fprintf(stdout, "Message is Signal.");         }                 if(DBUS_MESSAGE_TYPE_METHOD_CALL == dbus_message_get_type(msg))         {             fprintf(stdout, "Message is Method call.");     //        getchar();         }                                 if(dbus_message_is_method_call(msg, "test.Method.Call", "dbus_connection_borrow_message0"))             {                         called_dbus_connection_borrow_message0(msg, connection);             break;             }                 dbus_message_unref(msg);     }         dbus_connection_unref(connection); //    dbus_connection_close(connection); } -----------  End Server code --------------               <div> </div>Regards,Sumit Sumit Kumar JainCall me: +91-9880472974<div> </div></div> <hr size=1></hr> Chat on a cool, new interface.
