What does ~(uint32_t) mean?
c, syntax
Solution
`~()` is actually two things:
- `(uint32_t)` is a cast.
- `~` is a bitwise complement operator.
Problem
I'm reading a bit of C code in an OS kernel that says ``` x & ~(uint32_t)CST_IEc; ``` What does the `~()` mean? It's a tilde followed by parentheses!
