NAME
tcgetsid - get session ID
SYNOPSIS
#define _XOPEN_SOURCE 500 /* See feature_test_macros(7) */
#include <termios.h>

DESCRIPTION
The function tcgetsid() returns the session ID of the current session that has the terminal associated to fd as controlling terminal. This
terminal must be the controlling terminal of the calling process.

-1 is returned, and errno is set appropriately.
ERRORS
EBADF fd is not a valid file descriptor.
ENOTTY The calling process does not have a controlling terminal, or it has one but it is not described by fd.
VERSIONS
tcgetsid() is provided in glibc since version 2.1.
CONFORMING TO
POSIX.1-2001.
NOTES
This function is implemented via the TIOCGSID ioctl(2), present since Linux 2.1.71.
