Parameters

user_data	User data passed to HBBTV_DsmccRequestFile
err	result of file request - zero is success
data	Pointer to file data (only valid in callback function)
size	Length of file data

Function Documentation

void HBBTV_DBGSetMask ( U32BIT debug_mask )

Sets the debug mask.

Parameters

debug_mask

Bitmask of the following values (by default the relative prints are disabled)

HBBTV_DBG_THBBAPI: API between the HbbTV engine and the controlling application
HBBTV_DBG_TAIT: Application Information Table
HBBTV_DBG_TKEYS: Remote control keys
HBBTV_DBG_TAPP: HbbTV application lifecycle
HBBTV_DBG_TPVR: HbbTV PVR functionalities
HBBTV_DBG_TAV: Audio/Video related prints
HBBTV_DBG_TOBJS: Internal object handling

When the engine is compiled in release mode (see environment variable DTVKIT_BUILD_MODE) this function has no effect and no prints will be produced. In debug mode, if the debug mask is not set, the only active debug prints will be relative to errors and generic messages. The engine will use the function HBBTV_DBGPrint to print debug messages (see hbbtv_sif_debug.h)

Parameters

debug_mask Each bit in the mask corresponds to a group of debug prints, 1 means such prints are active, 0 inactive.
