Function rsix::process::membarrier_query[−][src]

pub fn membarrier_query() -> MembarrierQuery
Expand description

membarrier(MEMBARRIER_CMD_QUERY, 0, 0)—Query the supported membarrier commands.

This function doesn’t return a Result because it always succeeds; if the underlying OS doesn’t support the membarrier syscall, it returns an empty MembarrierQuery value.
