.TH KILL 2 .SH NAME kill \- terminate a process .SH SYNOPSIS .B int .B kill(pid) .br .B int pid; .fi .SH DESCRIPTION .I Kill will stop process .I pid and remove it from the system, returning SYSERR if the process id is invalid, OK otherwise. .I Kill terminates a process immediately. If the process has been queued on a semaphore, it is removed from the queue and the semaphore count is incremented as if the process had never been there. Processes waiting to send a message to a full port disappear without affecting the port. If the process is waiting for I/O, the I/O is stopped (if possible). .PP One can kill a process in any state, including a suspended one. Once killed, a process cannot recover. .SH BUGS At present there is no way to recover space allocated dynamically when a process terminates. However, .I kill does recover the stack space allocated to a process when it is created.
