Detailed Description

Function Documentation

int32_t SaSi_PalMemCmp	(	const void *	aTarget ,
		const void *	aSource ,
		uint32_t	aSize
	)

This function purpose is to compare between two given buffers according to given size.

Returns

The return values is according to operating system return values.

Parameters

[in]	aTarget	The target buffer to compare.
[in]	aSource	The Source buffer to compare to.
[in]	aSize	Number of bytes to compare.

void SaSi_PalMemCopy	(	void *	aDestination ,
		const void *	aSource ,
		uint32_t	aSize
	)

This function purpose is to copy aSize bytes from source buffer to destination buffer.

Returns

void.

Parameters

[out]	aDestination	The destination buffer to copy bytes to.
[in]	aSource	The Source buffer to copy from.
[in]	aSize	Number of bytes to copy.

void SaSi_PalMemFree

(

void *

aBuffer

)

This function purpose is to free allocated buffer.

Returns

void.

Parameters

[in]

aBuffer

Pointer to allocated buffer.

void* SaSi_PalMemMalloc

(

uint32_t

aSize

)

This function purpose is to allocate a memory buffer according to aSize.

Returns

The function will return a pointer to allocated buffer or NULL if allocation failed.

Parameters

[in]

aSize

Number of bytes to allocate.

void SaSi_PalMemMove	(	void *	aDestination ,
		const void *	aSource ,
		uint32_t	aSize
	)

This function purpose is to copy aSize bytes from source buffer to destination buffer. This function Supports overlapped buffers.

Returns

void.

Parameters

[out]	aDestination	The destination buffer to copy bytes to.
[in]	aSource	The Source buffer to copy from.
[in]	aSize	Number of bytes to copy.

void* SaSi_PalMemRealloc	(	void *	aBuffer ,
		uint32_t	aNewSize
	)

This function purpose is to reallocate a memory buffer according to aNewSize. The content of the old buffer is moved to the new location.

Returns

The function will return a pointer to the newly allocated buffer or NULL if allocation failed.

Parameters

[in]	aBuffer	Pointer to allocated buffer.
[in]	aNewSize	Number of bytes to reallocate.

void SaSi_PalMemSet	(	void *	aTarget ,
		const uint8_t	aChar ,
		uint32_t	aSize
	)

This function purpose is to set aSize bytes in the given buffer with aChar.

Returns

void.

Parameters

[out]	aTarget	The target buffer to set.
[in]	aChar	The char to set into aTarget.
[in]	aSize	Number of bytes to set.

void SaSi_PalMemSetZero	(	void *	aTarget ,
		uint32_t	aSize
	)

This function purpose is to set aSize bytes in the given buffer with zeroes.

Returns

void.

Parameters

[out]	aTarget	The target buffer to set.
[in]	aSize	Number of bytes to set.

SaSiStatus SaSi_PalSecMemCmp	(	const uint8_t *	aTarget ,
		const uint8_t *	aSource ,
		uint32_t	aSize
	)

This function purpose is to perform secured memory comparison between two given buffers according to given size. The function will compare each byte till aSize number of bytes was compared even if the bytes are different. The function should be used to avoid security timing attacks.

Returns

SASI_SUCCESS in case of success,

value on failure as defined in ssi_pal_error.h.

Parameters

[in]	aTarget	The target buffer to compare.
[in]	aSource	The Source buffer to compare to.
[in]	aSize	Number of bytes to compare.
