Description

Function Documentation

void EvrRtxMemoryInit	(	void *	mem,
		uint32_t	size,
		uint32_t	result
	)

Parameters

[in]	mem	pointer to memory pool.
[in]	size	size of a memory pool in bytes.
[in]	result	execution status: 1 - success, 0 - failure.

The event MemoryInit is generated when initialization of a variable size memory block completes.

Value in the Event Recorder shows:

• mem : memory address of memory pool.
• size : size of a memory pool in bytes.
• result : execution status: 1 - success, 0 - failure.

void EvrRtxMemoryAlloc	(	void *	mem,
		uint32_t	size,
		uint32_t	type,
		void *	block
	)

Parameters

[in]	mem	pointer to memory pool.
[in]	size	size of a memory block in bytes.
[in]	type	memory block type: 0 - generic, 1 - control block
[in]	block	pointer to allocated memory block or NULL in case of no memory is available.

The event MemoryAlloc is generated when allocation of a variable size memory block completes.

Value in the Event Recorder shows:

• mem : memory address of memory pool.
• size : size of a memory block in bytes.
• type : memory block type: 0 - generic, 1 - control block
• block : memory address of allocated memory block or 0 in case of no memory is available.

void EvrRtxMemoryFree	(	void *	mem,
		void *	block,
		uint32_t	result
	)

Parameters

[in]	mem	pointer to memory pool.
[in]	block	memory block to be returned to the memory pool.
[in]	result	execution status: 1 - success, 0 - failure.

The event MemoryFree is generated when deallocation of a variable size memory block completes.

Value in the Event Recorder shows:

• mem : memory address of memory pool.
• block : memory address of block to be returned to the memory pool.
• result : execution status: 1 - success, 0 - failure.

void EvrRtxMemoryBlockInit	(	osRtxMpInfo_t *	mp_info,
		uint32_t	block_count,
		uint32_t	block_size,
		void *	block_mem
	)

Parameters

[in]	mp_info	memory pool info.
[in]	block_count	maximum number of memory blocks in memory pool.
[in]	block_size	size of a memory block in bytes.
[in]	block_mem	pointer to memory for block storage.

The event MemoryBlockInit is generated when initialization of a fixed size memory block completes.

Value in the Event Recorder shows:

• mp_info : memory address of memory pool info.
• block_count : maximum number of memory blocks in memory pool.
• block_size : size of a memory block in bytes.
• block_mem : memory address of memory for block storage.

void EvrRtxMemoryBlockAlloc	(	osRtxMpInfo_t *	mp_info,
		void *	block
	)

Parameters

[in]	mp_info	memory pool info.
[in]	block	address of the allocated memory block or NULL in case of no memory is available.

The event MemoryBlockAlloc is generated when allocation of a fixed size memory block completes.

Value in the Event Recorder shows:

• mp_info : memory address of memory pool info.
• block : memory address of the allocated memory block or 0 in case of no memory is available.

void EvrRtxMemoryBlockFree	(	osRtxMpInfo_t *	mp_info,
		void *	block,
		int32_t	status
	)

Parameters

[in]	mp_info	memory pool info.
[in]	block	address of the allocated memory block to be returned to the memory pool.
[in]	status	extended execution status.

The event MemoryBlockFree is generated when deallocation of a fixed size memory block completes.

Value in the Event Recorder shows:

• mp_info : memory address of memory pool info.
• block : memory address of the allocated memory block to be returned to the memory pool.
• status : execution status osStatus_t
