Detailed Description

Macro Definition Documentation

◆ FALSE

#define FALSE 0

This ensures that RTEMS has FALSE defined in all situations.

◆ RTEMS_COMPILER_MEMORY_BARRIER

#define RTEMS_COMPILER_MEMORY_BARRIER ( )

The following macro is a compiler specific way to ensure that memory writes are not reordered around certain points. This specifically can impact interrupt disable and thread dispatching critical sections.

◆ RTEMS_CONTAINER_OF

#define RTEMS_CONTAINER_OF	(	_m,
		_type,
		_member_name
	)	( (_type *) ( (uintptr_t) ( _m ) - offsetof( _type, _member_name ) ) )

Returns a pointer to the container of a specified member pointer.

Parameters

[in]	_m	The pointer to a member of the container.
[in]	_type	The type of the container.
[in]	_member_name	The designator name of the container member.

◆ RTEMS_DECLARE_GLOBAL_SYMBOL

#define RTEMS_DECLARE_GLOBAL_SYMBOL ( _name ) extern char _name[]

Declares a global symbol with the specified name.

This macro must be placed at file scope.

The name must be a valid designator.

◆ RTEMS_DECONST

#define RTEMS_DECONST	(	_type,
		_var
	)	((_type)(uintptr_t)(const void *) ( _var ))

Removes the const qualifier from a type of a variable.

Parameters

[in]	_type	The target type for the variable.
[in]	_var	The variable.

◆ RTEMS_DEFINE_GLOBAL_SYMBOL

#define RTEMS_DEFINE_GLOBAL_SYMBOL	(	_name,
		_value
	)

Defines a global symbol with the specified name and value.

This macro must be placed at file scope.

The name must be a valid designator.

On the value parameters macro expansion is performed and afterwards it is stringified. It must expand to an integer literal understood by the assembler.

◆ RTEMS_DEPRECATED

typedef struct timespec rtems_thread_cpu_usage_t RTEMS_DEPRECATED

Public name for task floating point context area.

Represents the CPU usage per thread.

Information structure returned by the Heap Handler via the Region Manager.

Instructs the compiler to issue a warning whenever a variable or function with this attribute will be used.

When using nanoseconds granularity timing, RTEMS may internally use a variety of representations.

◆ RTEMS_DEQUALIFY

#define RTEMS_DEQUALIFY	(	_type,
		_var
	)	((_type)(uintptr_t)(const volatile void *) ( _var ))

Removes the all qualifiers from a type of a variable.

Parameters

[in]	_type	The target type for the variable.
[in]	_var	The variable.

◆ RTEMS_DEVOLATILE

#define RTEMS_DEVOLATILE	(	_type,
		_var
	)	((_type)(uintptr_t)(volatile void *) ( _var ))

Removes the volatile qualifier from a type of a variable.

Parameters

[in]	_type	The target type for the variable.
[in]	_var	The variable.

◆ RTEMS_HAVE_MEMBER_SAME_TYPE

#define RTEMS_HAVE_MEMBER_SAME_TYPE	(	_t_lhs,
		_m_lhs,
		_t_rhs,
		_m_rhs
	)	true

Evaluates to true if the members of two types have the same type.

Parameters

[in]	_t_lhs	Left hand side type.
[in]	_m_lhs	Left hand side member.
[in]	_t_rhs	Right hand side type.
[in]	_m_rhs	Right hand side member.

◆ RTEMS_INLINE_ROUTINE

#define RTEMS_INLINE_ROUTINE static inline

The following (in conjunction with compiler arguments) are used to choose between the use of static inline functions and macro functions. The static inline implementation allows better type checking with no cost in code size or execution speed.

◆ RTEMS_NO_INLINE

#define RTEMS_NO_INLINE

The following defines a compiler specific attribute which informs the compiler that the method must not be inlined.

◆ RTEMS_NO_RETURN

#define RTEMS_NO_RETURN

The following macro is a compiler specific way to indicate that the method will NOT return to the caller. This can assist the compiler in code generation and avoid unreachable paths. This can impact the code generated following calls to rtems_fatal_error_occurred and _Terminate.

◆ RTEMS_OBFUSCATE_VARIABLE

#define RTEMS_OBFUSCATE_VARIABLE ( _var ) (void) (_var)

Obfuscates the variable so that the compiler cannot perform optimizations based on the variable value.

The variable must be simple enough to fit into a register.

◆ RTEMS_PACKED

#define RTEMS_PACKED

Instructs the compiler that a specific structure or union members will be placed so that the least memory is used.

◆ RTEMS_PREDICT_FALSE

#define RTEMS_PREDICT_FALSE ( _exp ) ( _exp )

Returns the value of the specified integral expression and tells the compiler that the predicted value is false (0).

Parameters

[in] _exp The expression.

Returns: The value of the expression.

◆ RTEMS_PREDICT_TRUE

#define RTEMS_PREDICT_TRUE ( _exp ) ( _exp )

Returns the value of the specified integral expression and tells the compiler that the predicted value is true (1).

Parameters

[in] _exp The expression.

Returns: The value of the expression.

◆ RTEMS_PURE

#define RTEMS_PURE

The following defines a compiler specific attribute which informs the compiler that the method has no effect except the return value and that the return value depends only on parameters and/or global variables.

◆ RTEMS_STATIC_ASSERT

#define RTEMS_STATIC_ASSERT	(	cond,
		msg
	)

Value:

struct rtems_static_assert_ ## msg \

{ int rtems_static_assert_ ## msg : (cond) ? 1 : -1; }

msg

Definition: b1553brm.c:75

◆ RTEMS_UNUSED

#define RTEMS_UNUSED

Instructs the compiler that a specific variable is deliberately unused. This can occur when reading volatile device memory or skipping arguments in a variable argument method.

◆ TRUE

#define TRUE 1

This ensures that RTEMS has TRUE defined in all situations.

◆ RTEMS_DEPRECATED
