  OVERVIEW:
  
  This software unit holds the implementation of the external interfaces
  required by the WLAN BAP module.  It is currently a temporary 
  respository for API routines which should be furnished by CSR
  or TL, but aren't yet implemented.
  
  The functions provide by this module are called by the rest of 
  the BT-AMP PAL module.

  DEPENDENCIES: 

  Are listed for each API below.

  FUNCTION    WLANBAP_GetCurrentChannel

  DESCRIPTION 
    Clear out all fields in the BAP context.
    
  DEPENDENCIES 
    
  PARAMETERS 

    IN
    pBtampCtx:   pointer to the BAP control block
    channel:     current configured channel number.
    activeFlag:  flag indicating whether there is an active link.
   
  RETURN VALUE
    The result code associated with performing the operation  

    VOS_STATUS_E_FAULT:  pointer to return channel is NULL ; access would cause a page 
                         fault  
    VOS_STATUS_SUCCESS:  Everything is good :)
