[rtl] Problems faced to port a real time application to linux

["DEEPAK PRABHU" <kd_prabhu@hotmail.com>]

We want to use RT-Linux to develop a real time application,
for which we require details of system calls which can 
perform the following functions. 


1. To start a task which is not periodic.

2. To make a task wait, rt_task_wait() is it only for 
   periodic task or can it be used for non periodic 
   tasks also.

3. To make a task enter a critical region where other 
   tasks cannot interfere with the task in the critical
   region.

4. To make a task leave the critical region.

5. To read a device with timeout.

6. To start a task after a specified time but the task
   should not be periodic. It should be started only
   once.
7. Is there any method by which we can call real time
   system calls in the application, if so how.

8. To communicate with the application and modules 
   is FIFO the only mechanism.
   Writing and reading from FIFOs takes a lot of time 
   is there any other method of communicating apart
   from FIFOs.
