SL_HMAC_Update int SL_HASHCALL SL_HMAC_Update( void* pContext, const void* pSrc, unsigned int nSrcLength ); Return value Nonzero if update is successful, otherwise 0. In particular, this function returns 0 when the context was improperly initialized. Parameters pContext [in/out] Pointer to the context. pSrc [in] Pointer to the continuous memory block with which to update the context. nSrcLength [in] Length in bytes of the memory block. Remarks 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. Example See the example for SL_HMAC_Final.
