Top Forums Programming Changing stdin from file redirection to console input Post 7670 by nauman on Saturday 29th of September 2001 07:52:19 AM

Question

I am not opening any file in my program. The file is being redirected to stdin by the OS.

bin &lt inputfile

I am using gets() to read, which not to mention read from the stdin. After I am finished reading the file, I want gets() to continue reading from console input.

Are u implying that file redirection causes a fd attached to stdin. If so when I reopen the fd, what argument should I give it, to attach it to console input.

I am going to try it next anyway and see what happens.

Thanx

Nauman

NAME
pstopdf -- convert PostScript input into a PDF document. SYNOPSIS
pstopdf [inputfile] [-o outname] [-l] [-p] DESCRIPTION
pstopdf is a tool to convert PostScript input data into a PDF document. The input data may come from a file or may be read from stdin. The PDF document is always written to a file. The name of the output PDF file is derived from the name of the input file or may be explicitly named using the -o option. Flags: -o outname The name of the output file to create. If an explicit file name is not supplied, the output file will be created in the current directory and named foo.pdf for an input file named foo.ps -l Specifies that any messages generated during file conversion be written to a log file. For an output file named foo.pdf the generated log file is foo.pdf.log rather than generated to stdout. If there are no messages, the log file is not generated. -p Generates a simple progress message to stdout at the end of each page. Because conversion of complex or lengthy PostScript input can take time, it is sometimes useful to see that progress is being made. Progress messages are always written to stdout even when the -l (log file) option is specified. EXAMPLES
pstopdf inputfile.ps Creates a PDF file named inputfile.pdf from the PostScript data in the input file inputfile.ps pstopdf -o outputfilename Creates a PDF file named outputfilename from the PostScript data read from stdin. Apple Computer, Inc. May 31, 2019 Apple Computer, Inc.
