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

SYNOPSIS
       #include <stdlib.h>

       int grantpt(int fildes);

DESCRIPTION
       The grantpt() function changes the mode and ownership of the subsidiary
       pseudo-terminal  device  associated  with  its  manager pseudo-terminal
       counterpart. fildes is the file descriptor returned from  a  successful
       open  of  the  manager  pseudo-terminal device. The user ID of the sub‐
       sidiary is set to the real UID of the calling process and the group  ID
       is  set  to  a  reserved  group.  The permission mode of the subsidiary
       pseudo-terminal is set to  readable  and  writable  by  the  owner  and
       writable by the group.

RETURN VALUES
       Upon  successful completion, grantpt() returns 0. Otherwise, it returns
       −1 and sets errno to indicate the error.

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


       EINVAL    The fildes argument is not associated with a manager  pseudo-
                 terminal device.

                 be accessed.
