Step Two - Initializing SKTAL and registering SSN

The API function described in this section initalizes TAL and registers with LLC for use of a particular stack/SSN.

Application Code

// Initialize TAL layer. TAL initialization is done once

// at application startup.

ret = sktal_initializeTCAP()

if (ret != SK_OK)

{

fprintf(stderr, "Error initializing TCAP: %s\n", sk_errorText(ret));

skts_destroyConnection(CONN_ID);

return (SKTAL_EINVALIDARGS);

}

// register SSN with TCAP

// LOCAL_NODE - value created during configuration

// STACK_ID - Stack Id for the stack instance created during

// configuration.

// CONN_ID - Same as created in step one.

// LOCAL_PC - Local Point Code for stack instance.

// LOCAL_SSN - local subsyatem number for stack instance.

// newDialogue - Deafult Handler for handling new

// TCAP Transaction messages.

// instance - instance value returned after registeration is successful.

// This instance value is used while sending and receiving TCAP

// dialogues and components.

ret = sktal_registerTCAPSSNHandler (LOCAL_NODE, STACK_ID,

LOCAL_PC, LOCAL_SSN,

newDialogue, &instance, CONN_ID);

if (ret != SK_OK)

{

fprintf(stderr, "Error registering handler: %s\n", sk_errorText(ret));

skts_destroyConnection(CONN_ID);
