1 /* prio.c - prio command for BeOs, change priority of a given thread
2 * (c) 2001, 2002, François Revol (mmu_man) for OpenBeOS
3 * released under the MIT licence.
5 * ChangeLog:
6 * 04-26-2002 v1.2
7 * fixed a typo on error (Priority changed failed.)
8 * 04-25-2002 v1.1
9 * Initial. Used my renice.c code to rewrite 'prio' BeOS command for OpenBeOS.
11 * prio is a stripped-down version of renice
12 * seems to behave the same way as the original BeOS version. :)
