27 * Clients of the HAL call ath_hal_attach to obtain a reference to an ath_hal
28 * structure for use with the device. Hardware-related operations that
29 * follow must call back into the HAL through interface, supplying the
30 * reference as the first parameter.

44 * __ahdecl is analogous to _cdecl; it defines the calling
45 * convention used within the HAL. For most systems this
46 * can just default to be empty and the compiler will (should)
47 * use _cdecl. For systems where _cdecl is not compatible this
48 * must be defined. See linux/ah_osdep.h for an example.
