Function Documentation

mcuxCsslMemory_Set()

mcuxCsslMemory_Status_t mcuxCsslMemory_Set	(	mcuxCsslParamIntegrity_Checksum_t	chk,
		void *	pDst,
		uint8_t	val,
		uint32_t	length,
		uint32_t	bufLength )

Set length bytes of data at pDst.

The implementation is secure in the following aspects: Parameter integrity protection: the function returns immediately in case of an incorrect parameter checksum. Code flow protection: the function call is protected. Buffer overflow protection: no data is written to pDst beyond bufLength bytes.

Parameters

[in]	chk	The parameter checksum, generated with #MCUX_CSSL_PI_PROTECT.
[in]	pDst	The destination pointer to buffer to be set. Must not be NULL.
[in]	val	The byte value to be set.
[in]	length	The size in bytes to set.
[in]	bufLength	The buffer size (if bufLength < length, only bufLength bytes are set).

Returns

A status code encapsulated in a flow-protection type.

Return values

MCUXCSSLMEMORY_STATUS_OK	If val set length times at pDst.
MCUXCSSLMEMORY_STATUS_INVALID_PARAMETER	If one of the parameters is invalid.
MCUXCSSLMEMORY_STATUS_FAULT	If a fault was detected, included invalid checksum chk.
