+.Fn pthread_condattr_init "pthread_condattr_t *attr"
+.Ft int
+.Fn pthread_condattr_destroy "pthread_condattr_t *attr"
+.Sh DESCRIPTION
+Condition attribute objects are used to specify parameters to
+.Fn pthread_cond_init .
+FreeBSD's implementation of conditions does not support any non-default
+attributes, so these functions are not very useful, though they are required to
+to be present by POSIX.
+
+The
+.Fn pthread_condattr_init
+function initializes a condition attribute object with the default attributes.
+
+The
+.Fn pthread_condattr_destroy
+function destroys a condition attribute object.
+.Sh RETURN VALUES
+If successful, these functions return 0.
+Otherwise, an error number is returned to indicate the error.
+.Sh ERRORS
+.Fn pthread_condattr_init
+will fail if:
+.Bl -tag -width Er
+.It Bq Er ENOMEM
+Out of memory.
+.El
+
+.Fn pthread_condattr_destroy
+will fail if:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+Invalid value for
+.Fa attr .
