pub unsafe fn munlock(ptr: *mut c_void, len: usize) -> Result<()>Expand description
munlock(ptr, len)—Unlock memory.
Some implementations implicitly round the memory region out to the nearest page boundaries, so this function may unlock more memory than explicitly requested if the memory isn’t page-aligned.
§Safety
The range of memory starting at ptr, rounded down to the applicable page
boundary, and extending for len bytes, rounded up to the applicable page
size, must be valid to read with ptr’s provenance.
