  31 Install user-supplied library.
  32
  33 Install a user-supplied library specified by pathname in the current
  34 shell process. The library is used to resolve external references
  35 in programs and libraries loaded after its installation.  Note
  36 that the library is not loaded into the address space unless it is
  37 needed to resolve an external reference.  The list of inlibed
  38 libraries is passed to all children of the current shell.

  41 Returns success unless PATHNAME is not found or an error occurs.
