mem_prim_move()

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

extern

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 )

extern

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 )

extern

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 )

extern

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

mem_prim_set()

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

extern

mem_prim_set16()

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

extern

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_t's to be set
[in]	value	uint16_t value

mem_prim_set32()

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

extern

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
