Function Documentation

void DSPNetStackInitDone ( void *  apArg )

static

This is a callback function which is invoked when the LWIP stacks TCP timer and message queue threads are all initialized.

Note:

This callback sets a semaphore that the tcpip_stack_init() function is blocking on

Parameters:

[in]

apArg

Pointer to the semaphore to set.

Returns:

None

void DSPGetNetStackDefaults

(

tsDSPNetStackInit *

apSi

)

Call this function once on application startup to get the default stack constants which you will then pass into the DSPNetStackInit() function. After calling this function but before you call DSPNetStackInit(), you may modify the default values in the tsDSPNetStackInit structure.

Parameters:

[in]

apSi

Pointer to tsDSPNetStackInit structure to initialize.

Returns:

None

int DSPNetStackInit

(

tsDSPNetStackInit *

apSi

)

Call this function once on application startup to initialize the network stack internal memory structures.

Note:

You must first call DSPGetNetStackDefaults() it initialize the tsDSPNetStackInit structure that you pass into this function. Between the call to DSPGetNetStackDefaults() and the call to this function you may adjust the default values in the tsDSPNetStackInit structure to your applications needs.

Parameters:

[in]

apSi

Pointer to tsDSPNetStackInit structure.

Returns:

0 if successful
