asiowait(2)                                           asiowait(2)



NAME
     asiowait - wait for asynchronous I/O to complete

SYNOPSIS
     #include <sys/types.h>
     #include <sys/asio.h>

     int asiowait();

DESCRIPTION
     asiowait suspends the calling process until it detects the
     completion of its pending I/O operations initiated with
     either the asioread or the asiowrite system call.  The wait
     state initiated by asiowait can be interrupted by signals
     sent to the process that reactivate it.

     If there are no outstanding requests, control is returned
     immediately.

STATUS MESSAGES AND VALUES
     The asiowait system call returns 0 upon success or -1 if an
     error occurs.

     Upon an error, the value of errno is set to EINTR to
     indicate that the system call was interrupted by a signal.
