void
minusEqBits(
uint64_t* dstValue,
int dstIndex,
uint64_t srcValue,
int numBits);Bitwise MINUS the specified least-significant numBits in the specified srcValue from those in the specified dstValue starting at the specified dstIndex. The behavior is undefined unless 0 <= dstIndex, 0 <= numBits, and dstIndex + numBits <= k_BITS_PER_UINT64. Note that the bitwise difference, a - b, is defined in C++ code as a & ~b.
| Name | Description |
|---|---|
| dstValue | destination word to modify |
| dstIndex | index of the first destination bit |
| srcValue | source bits to subtract |
| numBits | number of bits to subtract |
