Function libuv::misc::os::setpriority

pub fn setpriority(pid: Pid, priority: i32) -> Result<()>

Sets the scheduling priority of the process specified by pid. The priority value range is between -20 (high priority) and 19 (low priority). The constants UV_PRIORITY_LOW, UV_PRIORITY_BELOW_NORMAL, UV_PRIORITY_NORMAL, UV_PRIORITY_ABOVE_NORMAL, UV_PRIORITY_HIGH, and UV_PRIORITY_HIGHEST are also provided for convenience in libuv_sys2.

Note: On Windows, this function utilizes SetPriorityClass(). The priority argument is mapped to a Windows priority class. When retrieving the process priority, the result will equal one of the UV_PRIORITY constants, and not necessarily the exact value of priority.

Note: On Windows, setting PRIORITY_HIGHEST will only work for elevated user, for others it will be silently reduced to PRIORITY_HIGH.
