wpauseoutput − pause output to a window

SYNOPSIS

int wpauseoutput(fd,value);
int fd;
int value;

DESCRIPTION

fd is an integer file descriptor for an opened Term0 window type device interface. 

value is the set/interrogate parameter.  Following are valid values for this parameter and the resulting effect:

-1 returns 0 if the window is not paused, otherwise it returns 1. 

0 resume output to the window.  On a Term0 window this is equivalent to XON. This is the default state at window create time. 

1 all output to the window is stopped (a paused condition).  On a Term0 window this is equivalent to an XOFF. 

DISCUSSION

This call inquires or sets whether to pause output to a window.  This routine works only with Term0 window types. 

DIAGNOSTICS

A return of -1 indicates failure; otherwise 0 or 1 is returned.  See errno(2) for further information.
