Constructor & Destructor Documentation

event_flags()

os::rtos::internal::event_flags::event_flags ( )

default

Construct an internal event flags object instance.

Member Function Documentation

check_raised()

bool os::rtos::internal::event_flags::check_raised	(	flags::mask_t	mask,
		flags::mask_t *	oflags,
		flags::mode_t	mode
	)

Check if expected flags are raised.

Parameters

[in]	mask	The expected flags (OR-ed bit-mask); if flags::any, any flag raised will do it.
[out]	oflags	Pointer where to store the current flags; may be nullptr.
[in]	mode	Mode bits to select if either all or any flags in the mask are expected, and if the flags should be cleared.

Return values

true	The expected flags are raised.
false	The expected flags are not raised.

Definition at line 77 of file os-flags.cpp.

clear()

result_t os::rtos::internal::event_flags::clear	(	flags::mask_t	mask,
		flags::mask_t *	oflags
	)

Clear event flags.

Parameters

[in]	mask	The OR-ed flags to clear.
[out]	oflags	Optional pointer where to store the previous value of the flags; may be nullptr.

Return values

result::ok	The flags were cleared.
EINVAL	The mask is zero.

Definition at line 158 of file os-flags.cpp.

get()

flags::mask_t os::rtos::internal::event_flags::get	(	flags::mask_t	mask,
		flags::mode_t	mode
	)

Get (and possibly clear) event flags.

Parameters

[in]	mask	The OR-ed flags to get/clear; can be flags::any.
[in]	mode	Mode bits to select if the flags should be cleared (the other bits are ignored).

Returns

The selected bits from the flags mask.

Definition at line 124 of file os-flags.cpp.

mask()

flags::mask_t os::rtos::internal::event_flags::mask ( void  )

inline

Get the flags mask.

Returns

The internal bit-mask.

Definition at line 208 of file os-flags.h.

raise()

result_t os::rtos::internal::event_flags::raise	(	flags::mask_t	mask,
		flags::mask_t *	oflags
	)

Raise event flags.

Parameters

[in]	mask	The OR-ed flags to raise.
[out]	oflags	Optional pointer where to store the new value of the flags; may be nullptr.

Return values

result::ok	The flags were raised.
EINVAL	The mask is zero.
ENOTRECOVERABLE	Raise failed.
