GRANTPT(P)		   POSIX Programmer's Manual		    GRANTPT(P)

NAME
       grantpt - grant access to the slave pseudo-terminal device

SYNOPSIS
       #include <stdlib.h>

       int grantpt(int fildes);

DESCRIPTION
       The grantpt() function shall change the mode and ownership of the slave
       pseudo-terminal device associated with its master pseudo-terminal coun‐
       terpart. The fildes argument is a file descriptor that refers to a mas‐
       ter pseudo-terminal device. The user ID of the slave shall  be  set  to
       the real UID of the calling process and the group ID shall be set to an
       unspecified group ID.  The permission mode of the slave pseudo-terminal
       shall be set to readable and writable by the owner, and writable by the
       group.

       The behavior of the grantpt() function is unspecified if	 the  applica‐
       tion has installed a signal handler to catch SIGCHLD signals.

RETURN VALUE
       Upon  successful	 completion,  grantpt()	 shall return 0; otherwise, it
       shall return -1 and set errno to indicate the error.

ERRORS
       The grantpt() function may fail if:

       EBADF  The fildes argument is not a valid open file descriptor.

       EINVAL The fildes argument is not associated with a master  pseudo-ter‐
	      minal device.

       EACCES The  corresponding  slave	 pseudo-terminal  device  could not be
	      accessed.
