What is the best way for a parent to kill a child thread that has blocked on a command it cannot finish and will never read another line of its code? Will pthread_cancel() work with a thread that will never stop processing its current line of code? Thanks.

wait

WAIT(1) 						    BSD General Commands Manual 						   WAIT(1)

NAME

     wait -- await process completion

SYNOPSIS

     wait [pid]

DESCRIPTION

     If invoked with no arguments, the wait utility waits until all existing child processes in the background have terminated.

     Available operands:

     pid     If a pid operand is specified, and it is the process ID of a background child process that still exists, the wait utility waits until
	     that process has completed and consumes its status information, without consuming the status information of any other process.

	     If a pid operand is specified that is not the process ID of a child background process that still exists, wait exits without waiting
	     for any processes to complete.

     The wait utility exits with one of the following values:

     0	     The wait utility was invoked with no operands and all of the existing background child processes have terminated, or the process
	     specified by the pid operand exited normally with 0 as its exit status.

     >0      The specified process did not exist and its exit status information was not available, or the specified process existed or its exit
	     status information was available, and it terminated with a non-zero exit status.

     If the specified process terminated abnormally due to the receipt of a signal, the exit status information of wait contains that termination
     status as well.

STANDARDS

     The wait command is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
