 .SH NAME
 condition \- concepts related to condition variables
 .SH DESCRIPTION

 Occasionally, a thread running within a mutex needs to wait for an event,  in
 which case it blocks or sleeps. When a thread is waiting for another thread to
 communicate its disposition, it uses a condition variable in conjunction with a
 mutex. Although a mutex is exclusive and the code it protects is sharable (at
 certain moments), condition variables enable the synchronization of differing

 and atomically releases the mutex that is waiting for the condition to change.
 If another thread changes the condition, it may wake up waiting threads by
 signaling the associated condition variable. The waiting threads, upon
 awakening, reacquire the mutex and re-evaluate the condition.
 .SS "Initialize"
-.sp
-.LP
 Condition variables and mutexes should be global. Condition variables that are
 allocated in writable memory can synchronize threads among processes if they
 are shared by the cooperating processes (see \fBmmap\fR(2)) and are initialized
 for this purpose.

 unless an attribute object is modified for inter-process prior to the
 initialization of the condition variable. Solaris condition variables also
 implement as the default,  intra-process; however, they set this attribute
 according to the argument, \fItype\fR, passed to their initialization function.
 .SS "Condition Wait"
-.sp
-.LP
 The condition wait interface allows a thread to wait for a condition and
 atomically release the associated mutex that it needs to hold to check the
 condition. The thread waits for another thread to make the condition true and
 that thread's resulting call to signal and wakeup the waiting thread.
 .SS "Condition Signaling"
-.sp
-.LP
 A condition signal allows a thread to unblock the next thread waiting on the
 condition variable, whereas, a condition broadcast allows a thread to unblock
 all threads waiting on the  condition variable.
 .SS "Destroy"
-.sp
-.LP
 The condition destroy functions destroy any state, but not the space,
 associated with the condition variable.
