ISATTY(3)                  Linux Programmer's Manual                 ISATTY(3)



NAME
       isatty - test whether a file descriptor refers to a terminal

SYNOPSIS
       #include <unistd.h>

       int isatty(int fd);

DESCRIPTION
       The  isatty()  function  tests  whether  fd  is an open file descriptor
       referring to a terminal.

RETURN VALUE
       isatty() returns 1 if fd is an open file descriptor referring to a ter‐
       minal; otherwise 0 is returned, and errno is set to indicate the error.

ERRORS
       EBADF  fd is not a valid file descriptor.

       ENOTTY fd  refers  to a file other than a terminal.  On some older ker‐
              nels, some types of files resulted in the error EINVAL  in  this
              case  (which  is a violation of POSIX, which specifies the error
              ENOTTY).
