Function Documentation

MCUX_CSSL_FP_PROTECTED_TYPE()

MCUX_CSSL_FP_PROTECTED_TYPE

(

mcuxCsslMemory_Status_t

)

Clear length bytes of data at pDst.

Deprecated type for mcuxClSession protected status codes.

Deprecated type for RSA protected status codes.

Deprecated type for error codes used by code-flow protected PKC component functions.

Deprecated type for error codes used by code-flow protected mcuxClMemory component functions.

Deprecated type for error codes used by code-flow protected Math component functions.

Deprecated type for Key component error codes, returned by functions with code-flow protection.

Deprecated type for ELS driver protected status codes.

Deprecated type for mcuxClEcc component return codes.

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 dstLength bytes.

Parameters

[in]	chk	The parameter checksum, generated with mcuxCsslParamIntegrity_Protect.
[in]	pDst	The destination pointer to buffer to be cleared. Must not be NULL.
[in]	dstLength	The size of the destination data buffer in bytes.
[in]	length	The number of bytes to clear. Must be different from zero.

Returns

A status code encapsulated in a flow-protection type.

Return values

MCUXCSSLMEMORY_STATUS_OK	If the contents in buffer at pDst is cleared.
MCUXCSSLMEMORY_STATUS_INVALID_PARAMETER	If one of the parameters is invalid.
MCUXCSSLMEMORY_STATUS_FAULT	If a fault was detected, included invalid checksum chk.
