nice -- set nice value


nice is as specified in the Single UNIX Specification, but with differences as listed below.

As deprecated behavior, the return value of a successful call to nice may be 0 (rather than the new nice value). A future version of the LSB is expected to require the new nice value, as specified in the Single UNIX Specification. But until then, applications need to call the getpriority, rather than rely on the return value from nice.
