NAME

wconceal − conceal window

SYNOPSIS

int wconceal(fd,value);
int fd;
int value;

DESCRIPTION

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

value is the set/interrogation parameter which determines the action taken by this routine; valid values are:

-1 return whether the window is concealed (0, means no; 1 means yes). 

0 then the window’s state is not changed−the routine does nothing. 

1 set the window or icon to be concealed. 

DISCUSSION

This call inquires or sets the value of the window’s visibility.  wconceal must be false for anything to be visible.  Being not concealed does not guarantee visibility, because it might be obscured via another window or by the screen edges itself. 

SEE ALSO

wtop(3W),wbottom(3W),wshuffle(3W). 

DIAGNOSTICS

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