 .Pp
 The
 .Fn pthread_mutexattr_destroy
 function destroys

-.Pp
-The
-.Fn pthread_mutexattr_settype
-function sets the mutex type value of the attribute.  Valid mutex types are:
-.Dv PTHREAD_MUTEX_NORMAL ,
-.Dv PTHREAD_MUTEX_ERRORCHECK ,
-.Dv PTHREAD_MUTEX_RECURSIVE ,
-and
-.Dv PTHREAD_MUTEX_DEFAULT .
-The default mutex type for

-.Pp
-.Dv PTHREAD_MUTEX_NORMAL
-mutexes do not check for usage errors.
-.Dv PTHREAD_MUTEX_NORMAL
-mutexes will deadlock if reentered, and result in undefined behavior if a
-locked mutex is unlocked by another thread.  Attempts to unlock an already
-unlocked
-.Dv PTHREAD_MUTEX_NORMAL
-mutex will result in undefined behavior.
-.Pp
-.Dv PTHREAD_MUTEX_ERRORCHECK
-mutexes do check for usage errors.
-If an attempt is made to relock a
-.Dv PTHREAD_MUTEX_ERRORCHECK
-mutex without first dropping the lock, an error will be returned.
-If a thread attempts to unlock a
-.Dv PTHREAD_MUTEX_ERRORCHECK
-mutex that is locked by another thread, an error will be returned.  If a
-thread attempts to unlock a
-.Dv PTHREAD_MUTEX_ERRORCHECK
-thread that is unlocked, an error will be returned.
-.Pp
-.Dv PTHREAD_MUTEX_RECURSIVE
-mutexes allow recursive locking.
-An attempt to relock a
-.Dv PTHREAD_MUTEX_RECURSIVE
-mutex that is already locked by the same thread succeeds.  An equivalent
-number of
-.Xr pthread_mutex_unlock 3
-calls are needed before the mutex will wake another thread waiting on this
-lock.  If a thread attempts to unlock a
-.Dv PTHREAD_MUTEX_RECURSIVE
-mutex that is locked by another thread, an error will be returned.  If a thread attemps to unlock a
-.Dv PTHREAD_MUTEX_RECURSIVE
-thread that is unlocked, an error will be returned.
-.Pp
-.Dv PTHREAD_MUTEX_DEFAULT
-mutexes result in undefined behavior if reentered.
-Unlocking a
