Function Documentation¶
Fapi_NvWrite (FAPI_CONTEXT * context, char const * nvPath, uint8_t const * data, size_t size)¶
One-Call function for Fapi_NvWrite
Writes data to a 'regular' (not pin, extend or counter) NV index.
Parameters:
context The FAPI_CONTEXT
nvPath The path of the NV index to write
data The data to write to the NV index
size The size of data in bytes
nvPath The path of the NV index to write
data The data to write to the NV index
size The size of data in bytes

TSS2_RC_SUCCESS if the function call was a
success.
