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