| Issue |
We changed a priority of a process from 9 to 13, and found mouse and keyboard failed to work. The priority of mouse is 12, which is the default setting. If we want to change the priority of a PhAB application, where does one set the priority? In abmain.c?

| Solution |
For setting the priority, look at the setprio() function in Watcom. An application that uses it can be put in startup, or as an initlization function.
From the Watcom docs:
-----
setprio
- set the priority of a process
Synopsis:
#include <sched.h>
int setprio( pid_t pid, int prio );
Description:
The setprio() function changes the priority of thread 1 of process pid to priority prio. If pid is zero, the priority of the calling thread is set.
