Function Documentation

void sys_set_max_lwip_threads

(

int

anMaxTasks

)

Set number of threads allowed to use lwIP concurrently.

Note:

Must be called prior to stack initialization.

Parameters:

[in]

anMaxTasks

Maximum lwIP threads allowed.

Returns:

None.

int sys_get_max_lwip_threads

(

void

)

Get number of threads allowed to use lwIP concurrently.

Returns:

Concurrent threads allowed.

void sys_set_mbx_queue_entries

(

int

anMbxEntries

)

Set number of queue entries created in lwIP mailboxes.

Note:

Must be called prior to stack initialization.

Parameters:

[in]

anMbxEntries

Number of entries to create.

Returns:

None.

int sys_get_mbx_queue_entries

(

void

)

Get number of queue entries used in lwIP mailboxes.

Returns:

Queue entries configured.

int sys_thread_register

(

sys_thread_t

ahThread

)

Attempt to register a specified thread with lwIP.

Parameters:

[in]

ahThread

Handle of thread to register.

Returns:

Index into timeout structure (if successful), or -1 if failed.

int sys_thread_unregister

(

sys_thread_t

ahThread

)

Attempt to un-register a specified thread with lwIP.

Parameters:

[in]

ahThread

Handle of thread to register.

Returns:

0 (if successful), or -1 if failed.

int sys_thread_priority	(	sys_thread_t	ahThread,
		int	anPrio
	)

Attempt to change the priority of a previously created thread.

Parameters:

[in]	ahThread	Handle of thread to register.
[in]	anPrio	New thread priority.

Returns:

Index into timeout structure (if successful), or -1 if failed.
