NAME

renice − set program priority

SYNOPSIS

renice(pid,nice)

DESCRIPTION

Renice sets the scheduling priority of the process with id pid to nice.  The superuser may renice any process to any value from -127 to 127. Other users may only increase the nice value of one of their own processes. 

DIAGNOSTICS

Renice will fail and the process’s scheduling priority will be unaltered if:

[EPERM] The named process’s effective user ID is not the same as the calling process and the process’s effective user ID is not the superuser. 

[ESRCH] The named process does not exist.
