.PP 
This is an RTLinux v1.x compatibility function. 
For new programs, please see \fBpthread_wait_np(3)\fP. 
.SH "DESCRIPTION" 
.PP 
\fBrt_task_wait\fP blocks the currently running realtime task until the start of the next period.  The task was previously marked for execution using \fBrt_task_make_periodic\fP. 
.PP 
The task is not suspended; this is done instead by \fBrt_task_suspend\fP.  Instead, it simply gives up control until the next time period. 
.SH "RETURN VALUE" 
.PP 
Always returns 0. 
.SH "ERRORS" 
.PP 
None.
