Get File Descriptor Of Stdout. Syscalls like open(2) or pipe(2) or socket(2). In linux, there are three types of file descriptors that are commonly used by programs and commands: Standard input (stdin), standard output (stdout), and standard error (stderr). You could test with isatty(3) if it is a tty, and/or use fstat(2) to get status information on it. In perl, specify a shell redirection as the file name to. &>filename # redirect both stdout and stderr to file filename. # this operator is now functional, as of bash 4, final release. This initialization cannot be combined with the declaration of fout, as stdout is not (at least, not necessarily) a constant. A general rule is that file descriptors are handled in the kernel, while stdio is just a library. This is a file descriptor that represents the standard input stream, which is used to read input data from the user or from another program. In c, call read or write with whatever fd you want, or call fdopen to get an stdio stream. This means for example, that after an exec (3), the.
