BitVecByteSize
BitVecByteSizeDescription
Get u64 of bitvector in bytes. This returns the actual memory used by the bit data.
Parameters
| Name | Direction | Description |
|---|---|---|
bv | in | Bitvector to get byte u64 of |
Usage example (from documentation)
u64 bytes_used = BitVecByteSize(&flags);
Usage example (Cross-references)
result = result && (BitVecCapacity(&bv) == 0);
result = result && BitVecEmpty(&bv);
result = result && (BitVecByteSize(&bv) == 0);
// Add bits and test macros again
result = result && (BitVecCapacity(&bv) >= 65);
result = result && !BitVecEmpty(&bv);
result = result && (BitVecByteSize(&bv) >= 9); // At least 9 bytes for 65 bits
// Test with exactly power-of-2 sizes
result = result && (BitVecLen(&bv) == 64);
result = result && (BitVecByteSize(&bv) >= 8); // At least 8 bytes for 64 bits
BitVecDeinit(&bv);
