     PTOPEN(3)                                               PTOPEN(3)

     NAME
          ptopen - find and open a pseudo-terminal file

     SYNOPSIS
          int ptopen (name)
          char *name;

     DESCRIPTION
          Ptopen searches for a pseudo-terminal file pair it can open.
          If successful, it returns a file descriptor for the odd-
          numbered member of the pair, and places the name of the
          even-numbered member in name. There must be enough room in
          name to contain the full pathname.  If unsuccessful, ptopen
          returns a negative value.
