Loads and initializes the NMS GR303 library.
NMS_GR303_RESULT_T NMS_GR303Initialize ( NMS_GR303_BOARD_FAMILY_T board_family, void *init_parms)
|
Argument |
Description |
|
board_family |
Specifies the board family used on the system. The NMS_GR303_BOARD_FAMILY_T type is defined in the following structure: typedef enum _NMS_GR303_BOARD_FAMILY_T |
|
init_parms |
Pointer to board-specific initialization parameters. For CG 6000 or CG 6000C boards, the application passes NULL. For CG 6100C and CG 6500C boards, the application passes a CTA context handle on which the Switching (SWI) service has been opened. |
|
Return value |
Description |
|
NMSGR303_SUCCESS |
|
|
NMSGR303_ALREADY_INITIALIZED |
NMS GR303 library is already initialized. |
|
NMSGR303_FAILED_LOAD_LIB |
Failed to load the library. |
|
NMSGR303_INTERNAL_FAILURE |
Failed to initialize internal structures, connections or processes. |
|
NMSGR303_NO_MEMORY |
Failed to allocate memory. |
NMS_GR303Initialize loads and initializes the NMS GR303 library. Applications invoke this function only once at start-up time, and before invoking any other NMS GR303 library functions.
If the system uses CG 6000 or CG 6000C boards, the application passes NULL as the init_parms argument.
When invoking NMS_GR303Initialize on systems that use CG 6100C or CG 6500C boards, applications use the init_parms argument to pass a pointer to a CTA context handle on which the Switching service is opened. When CG 6100C or CG 6500C boards reside in the system, applications must perform the following Natural Access operations before initializing the NMS GR303 library:
Invoke ctaInitialize with the list of services including the Switching service.
Invoke ctaCreateQueue to create an event queue.
Invoke ctaCreateContext to create a context.
Invoke ctaOpenServices to open appropriate Natural Access services, including the Switching service, on the context.
ctaOpenServices returns a context handle that the application passes to the NMS GR303 library when invoking NMS_GR303Initialize.
If the application wants the NMS GR303 library to return trace information, it should invoke NMS_GR303SetTrace immediately after invoking NMS_GR303Initialize.
