Member Function Documentation
◆ MBEDTLS_PRIVATE() [1/3]
| uint32_t psa_drv_se_t::MBEDTLS_PRIVATE | ( | hal_version |
|
) |
The version of the driver HAL that this driver implements.
This is a protection against loading driver binaries built against a different version of this specification. Use PSA_DRV_SE_HAL_VERSION .
◆ MBEDTLS_PRIVATE() [2/3]
| size_t psa_drv_se_t::MBEDTLS_PRIVATE | ( | persistent_data_size |
|
) |
The size of the driver's persistent data in bytes.
This can be 0 if the driver does not need persistent data.
See the documentation of psa_drv_se_context_t::persistent_data for more information about why and how a driver can use persistent data.
◆ MBEDTLS_PRIVATE() [3/3]
| psa_drv_se_init_t psa_drv_se_t::MBEDTLS_PRIVATE | ( | p_init |
|
) |
The driver initialization function.
This function is called once during the initialization of the PSA Cryptography subsystem, before any other function of the driver is called. If this function returns a failure status, the driver will be unusable, at least until the next system reset.
If this field is
NULL
, it is equivalent to a function that does nothing and returns
PSA_SUCCESS
.
