Currently we only allow users to get and set number of queues. The operation is always non blocking. There is no provision for non blocking operation at the moment. The queue sizes are set to MAX 256 by default. If a user changes the attributes and sets the queue size or number of messages in a queue to less than 256, it is the responsibility of the user to close any queues which were opened with a descriptor greater than the value currently set. For example, by default queue sizes are 256. If 150 queues are opened and then the user sets the number of queues to 32, all open descriptors and queues from 32 to 150 must be closed. Note that descriptor number allocation starts with zero and not one.

/* Function prototypes for the system library. The prototypes in this file
|
|
* are undefined to NULL if the kernel call is not enabled in config.h.
|
|
* The implementation is contained in src/kernel/system/.
|
|
*
|
|
* The system library allows to access system services by doing a kernel call.
|
|
* System calls are transformed into request messages to the SYS task that is
|
|
* responsible for handling the call. By convention, sys_call() is transformed
|
|
* into a message with type SYS_CALL that is handled in a function do_call().
|
|
*
|
|
* Changes:
|
|
* Mar 01, 2010 SYS_CLEAR and SYS_EXIT split (Cristiano Giuffrida)
|
|
* Jul 30, 2005 created SYS_INT86 to support BIOS driver (Philip Homburg)
|
|
* Jul 13, 2005 created SYS_PRIVCTL to manage services (Jorrit N. Herder)
|
|
* Jul 09, 2005 updated SYS_KILL to signal services (Jorrit N. Herder)
|
|
* Jun 21, 2005 created SYS_NICE for nice(2) kernel call (Ben J. Gras)
|
|
* Jun 21, 2005 created SYS_MEMSET to speed up exec(2) (Ben J. Gras)
|
|
* Jan 20, 2005 updated SYS_COPY for virtual_copy() (Jorrit N. Herder)
|
|
* Oct 24, 2004 created SYS_GETKSIG to support PM (Jorrit N. Herder)
|
|
* Oct 10, 2004 created handler for unused calls (Jorrit N. Herder)
|
|
* Sep 09, 2004 updated SYS_EXIT to let services exit (Jorrit N. Herder)
|
|
* Aug 25, 2004 rewrote SYS_SETALARM to clean up code (Jorrit N. Herder)
|
|
* Jul 13, 2004 created SYS_SEGCTL to support drivers (Jorrit N. Herder)
|
|
* May 24, 2004 created SYS_SDEVIO to support drivers (Jorrit N. Herder)
|
|
* May 24, 2004 created SYS_GETINFO to retrieve info (Jorrit N. Herder)
|
|
* Apr 18, 2004 created SYS_VDEVIO to support drivers (Jorrit N. Herder)
|
|
* Feb 24, 2004 created SYS_IRQCTL to support drivers (Jorrit N. Herder)
