Re: Stop process to wait for a signal to hapen

[Murilo Tuvani <murilo_tuvani yahoo com br>]

I want to stop the hole aplication while the event

on_button_data_entered_ok

doesn´t hapen. the problem is.

when I make

 

this funciton will return and my program is a Virtual Machine, so it must stop while the user doesn´t enter the data, if it doesn´t stop the callig functions....

 

execute_read()

{

  GtkWidget *window_enter_data;

  char          *mydata;

 

  window_enter_data=create_window_enter_data();

  gtk_widget_show(window_enter_data);

 

  mydata = strdup(gtk_entry_get_text(entry_data));

 

  ....

  ///mydata will contain trash!!

}

 

void execute()

{

   while (instruction!=NULL)

  {

     ...

     if(!strcmp(instruction->opcode,"rd"))

     {

        execute_read();

     }

     ...

 

     instruction=instruction->next;

  }

}

will continue and get thash, but I´m looking for a solution using semaphores
