	I am writing a graphics application which I would like to
use ghostscript to do the actual imaging.  I thought the easiest
way for me to do this was to open a pipe to gs and just write PostScript
to it, but I am having a little trouble with this.  The following is the
program I am using to test my idea.

	#include <stdio.h>
	 
	main()
	{
	  extern char *gets();
	 
	  FILE *gs = popen( "./gs -", "w" );
	  char input_line[ 100 ];
	 
	  while ( gets( input_line ) != NULL ) {
	    fputs( input_line, gs );
	    putc( '\n', gs );
	    fflush( gs );
	  }
	}

	There are two problems that I have.  One is that the input
data doesn't seem to be getting to gs in a timely fashion.  If I
run my test program using the tty as the standard input, none of my
PostScript graphics appear in the ghostscript window as I enter them.
I have to enter EOF and then only some of the graphics appear.  For
example, *half* of a line appears.  If I redirect input from a file,
all is fine.

	I am running on a color Sun SPARCstation 1 running
SunOS 4.1.1 with with ghostscript 2.5.2.

	Thanks in advance.
