I have a C program which calls nice(19) on linux to put the process at
the lowest priority , what value should be used under cygwin ?
and is the value the same for NT,95,98 ?
Thanks

Cygwin processes can be set to:
IDLE_PRIORITY_CLASS
NORMAL_PRIORITY_CLASS
HIGH_PRIORITY_CLASS
REALTIME_PRIORITY_CLASS
using the nice() call. NORMAL_PRIORITY_CLASS is the default.
If you pass a positive number to nice(), then the priority level will
decrease by one (within the above priority list). A negative number
would make it increase by one. It is not possible to change it by
more than one at a time without making repeated calls. An increment
above REALTIME_PRIORITY_CLASS results in the process staying at that
priority. Likewise, a decrement to IDLE_PRIORITY_CLASS has it stay at
that priority.
Note that in the Win32 API, there are 32 priorities. So we only give
access to four of these through nice() currently.
