Function Documentation

static int attach	(	l4_threadid_t	client,
		omega0_irqdesc_t	desc
	)			[static]

Attach the client to the given irq.

Currently, only one irq per client possible.

Return values:

	0	- success
	<0	- error,
	>0	- lthread

Definition at line 37 of file server.c.

static int detach	(	l4_threadid_t	client,
		int	irq,
		int	cmp_task
	)			[static]

detach from a given irq.

Definition at line 103 of file server.c.

static int detach_all

(

int

task

)

[static]

detach from a given client.

static int first

(

void

)

[static]

Iterator: First handle

Iterator: Next handle

static int pass	(	l4_threadid_t	client,
		omega0_irqdesc_t	desc,
		l4_threadid_t	new_client
	)			[static]

Pass IRQ to other thread.

Bug:

It may happen that the detach is successful, but not so the attach. at the result, the irq is free (!!!!)

Definition at line 160 of file server.c.

void server

(

void

)

The server itself.

All initialization stuff like creating the receive- threads which are attached to their irqs is already done.
