A problem with a program I have written (which pipes information to ghostscript) prompted me to check the following cat | gs -sDEVICE=ppmraw - which gives the result from cat(as soon as a newline is entered) cat: stdin: Resource temporarily unavailable (i.e. the error EAGAIN). I am using 4-STABLE, tcsh as the shell and gs6.01. Is ghostscript at fault? In my program, ensuring that all the standard descriptors(stdin,stdout and stderr) were closed before the exec, solved the problem. Is there some way that ghostscript can influence stdin when it only has access to stderr? I tried search the ghostscript code for an explanation, but I could not find any ioctl or fcntl calls relating to the standard descriptors. Thank you for any suggestions.
