Data Structures
struct	pbl_timeout_t
	Timeout of a blocking call. More...

Macros
#define	PBL_TICK_HZ   CONFIG_KERNEL_TICK_HZ
	Tick rate in Hz, from CONFIG_KERNEL_TICK_HZ.
#define	PBL_TICK_FOREVER   UINT32_MAX
	Tick count that stands for an infinite timeout.
#define	PBL_NO_WAIT   ((pbl_timeout_t){.ticks = 0})
	Do not wait: fail with -EBUSY if the call would block.
#define	PBL_FOREVER   ((pbl_timeout_t){.ticks = PBL_TICK_FOREVER})
	Wait without a time limit.
#define	PBL_TICKS(t)   ((pbl_timeout_t){.ticks = (t)})
	Timeout in ticks.
#define	PBL_MSEC(ms)   ((pbl_timeout_t){.ticks = pbl_ms_to_ticks(ms)})
	Timeout in milliseconds, rounded down to whole ticks.
#define	PBL_SEC(s)   PBL_MSEC((s) * 1000U)
	Timeout in seconds.
#define	PBL_PRIO_IDLE   ((pbl_prio_t)0)
	Lowest priority, the one of the idle thread.
#define	PBL_PRIO_MAX   ((pbl_prio_t)(CONFIG_KERNEL_NUM_PRIORITIES - 1))
	Highest priority, CONFIG_KERNEL_NUM_PRIORITIES - 1.

Typedefs
typedef uint32_t	pbl_tick_t
	Kernel tick count.
typedef uint8_t	pbl_prio_t
	Thread priority.

Functions
pbl_tick_t	pbl_ms_to_ticks (uint32_t ms)
	Convert milliseconds to ticks, rounding down.
uint32_t	pbl_ticks_to_ms (pbl_tick_t ticks)
	Convert ticks to milliseconds, rounding down.
static bool	pbl_timeout_is_forever (pbl_timeout_t t)
	Check whether a timeout is PBL_FOREVER.
static bool	pbl_timeout_is_no_wait (pbl_timeout_t t)
	Check whether a timeout is PBL_NO_WAIT.
