Set process priority
Source position: bunxh.inc line 104
function fpNice( |
N: cint |
):cint; |
Nice adds -N to the priority of the running process. The lower the priority numerically, the less the process is favored. Only the superuser can specify a negative N, i.e. increase the rate at which the process is run.
If the function is successful, zero is returned. On error, a nonzero value is returned.
Extended error information is returned by the FpGetErrno function.
