int SL_HASHCALL SL_HMAC_Update( void*
pContext, const void* pSrc, unsigned int nSrcLength
Nonzero if update is successful, otherwise 0. In particular, this function
returns 0 when the context was improperly initialized.
[in/out] Pointer to the context.
[in] Pointer to the
continuous memory block with which to update the context.
[in] Length in bytes
of the memory block.
Updates the context pointed by pContext with the memory block
pointed by pSrc. Call this function for each continuous memory
block of the data for which the HMAC is calculated. To retrieve the HMAC after using
SL_HMAC_Update, call SL_HMAC_Final or SL_HMAC_FinalHex.
