Description

AE_VLES16C.IC is a 16-bit conditional bit stream store for variable-length encode. 16 bits are stored to the bit stream pointed to by a if doing so is needed to maintain the invariant that fewer than 16 bits are buffered in AE_BITHEAD and a is advanced by 2 with a circular wrap-around.
