Proto:void poly1305_update_generic(struct poly1305_desc_ctx *desc, const u8 *src, unsigned int nbytes)

Type:void

Parameter:

const u8 *src
unsigned intnbytes
176  If Value for the false possibility is greater at compile time( bytes used in partial buffer ) Then
177  bytes = min - return minimum of two values of the same or compatible types*@x: first value*@y: second value(nbytes, POLY1305_BLOCK_SIZE - bytes used in partial buffer )
178  No 3D Now!( partial buffer + bytes used in partial buffer , src, bytes)
179  src += bytes
180  nbytes -= bytes
181  bytes used in partial buffer += bytes
183  If bytes used in partial buffer == POLY1305_BLOCK_SIZE Then
184  poly1305_core_blocks( & accumulator , key , partial buffer , 1, 1)
185  bytes used in partial buffer = 0
189  If Value is more likely to compile time(nbytes >= POLY1305_BLOCK_SIZE) Then

192  src += nbytes - nbytes % POLY1305_BLOCK_SIZE
