Function Documentation

mem_prim_set()

void mem_prim_set	(	void *	dest,
		uint32_t	len,
		uint8_t	value
	)

Sets len bytes starting at dest to the specified value.

Parameters

[out]	dest	pointer to memory that will be set to value
[in]	len	number of bytes to be set
[in]	value	byte value

mem_prim_set16()

void mem_prim_set16	(	uint16_t *	dest,
		uint32_t	len,
		uint16_t	value
	)

Sets len uint16_t's starting at dest to the specified value.

Pointers must meet system alignment requirements.

Parameters

[out]	dest	pointer to memory that will be set to value
[in]	len	number of uint16_ts to be set
[in]	value	uint16_t value

mem_prim_set32()

void mem_prim_set32	(	uint32_t *	dest,
		uint32_t	len,
		uint32_t	value
	)

Sets len uint32_t's starting at dest to the specified value.

Pointers must meet system alignment requirements.

Parameters

[out]	dest	pointer to memory that will be set to value
[in]	len	number of uint32_t's to be set
[in]	value	uint32_t value

mem_prim_move()

void mem_prim_move	(	void *	dest,
		const void *	src,
		uint32_t	len
	)

Moves at most len of bytes from src to dest.

Dest may overlap with src.

Parameters

[out]	dest	pointer to the memory that will be replaced by src.
[in]	src	pointer to the memory that will be copied to dest
[in]	len	maximum number bytes of src that can be copied

mem_prim_move8()

void mem_prim_move8	(	uint8_t *	dest,
		const uint8_t *	src,
		uint32_t	len
	)

Moves at most len of uint8_t's from src to dest.

The destination may overlap with source.

Parameters

[out]	dest	pointer to the memory that will be replaced by src
[in]	src	pointer to the memory that will be copied to dest
[in]	len	maximum number uint8_t of src that can be copied

mem_prim_move16()

void mem_prim_move16	(	uint16_t *	dest,
		const uint16_t *	src,
		uint32_t	len
	)

Moves at most len uint16_t's from src to dest.

The destination may overlap with source.

Parameters

[out]	dest	pointer to the memory that will be replaced by src.
[in]	src	pointer to the memory that will be copied to dest
[in]	len	maximum number uint16_t of src that can be copied

mem_prim_move32()

void mem_prim_move32	(	uint32_t *	dest,
		const uint32_t *	src,
		uint32_t	len
	)

Moves at most len of uint32_t's from src to dest.

The destination may overlap with source.

Parameters

[out]	dest	pointer to the memory that will be replaced by src.
[in]	src	pointer to the memory that will be copied to dest
[in]	len	maximum number uint32_t of sp that can be copied
