  UNLOCKPT(3C)             Standard C Library Functions             UNLOCKPT(3C)
  
  NAME
!        unlockpt - unlock a pseudo-terminal master/slave pair
  
  SYNOPSIS
         #include <stdlib.h>
  
!        int unlockpt(int fildes);
  
- 
  DESCRIPTION
!        The unlockpt() function unlocks the slave pseudo-terminal device
!        associated with the master to which fildes refers.
  
  
-        Portable applications must call unlockpt() before opening the slave
-        side of a pseudo-terminal device.
- 
  RETURN VALUES
!        Upon successful completion, unlockpt() returns 0. Otherwise, it returns
!        -1 and sets errno to indicate the error.
  
  ERRORS
         The unlockpt() function may fail if:
  
!        EBADF
!                  The fildes argument is not a file descriptor open for
                   writing.
  
  
!        EINVAL
!                  The fildes argument is not associated with a master pseudo-
!                  terminal device.

  UNLOCKPT(3C)             Standard C Library Functions             UNLOCKPT(3C)
  
  NAME
!      unlockpt - unlock a pseudo-terminal device pair
  
  SYNOPSIS
       #include <stdlib.h>
  
!      int
!      unlockpt(int fildes);
  
  DESCRIPTION
!      When a pseudo-terminal manager device is opened, whether through
!      posix_openpt(3C) or open(2) on a ptm(7D) device, the subsidiary device
!      begins operation in a locked state.  The unlockpt() function unlocks the
!      pseudo-terminal subsidiary device associated with the manager device to
!      which fildes refers.
  
+      Portable applications must call unlockpt() before opening the pseudo-
+      terminal subsidiary device.
  
  RETURN VALUES
!      The unlockpt() function returns the value 0 if successful; otherwise the
!      value -1 is returned and the global variable errno is set to indicate the
!      error.
  
+ EXAMPLES
+      See posix_openpt(3C) for an example that includes a call to unlockpt().
+ 
  ERRORS
       The unlockpt() function may fail if:
  
!      EBADF              The fildes argument is not a file descriptor open for
                          writing.
  
+      EINVAL             EINVAL The fildes argument is not associated with a
+                         pseudo-terminal manager device.
