  55. returns the value of a tag or pseudo-tag associated with the
  56. the current directory of the opened <small>TIFF</small> file
  57. <i>tif</i>. (A <i>pseudo-tag</i> is a parameter that is used
  58. to control the operation of the <small>TIFF</small> library
  59. but whose value is not read or written to the underlying
  60. file.) The file must have been previously opened with
  61. <i>TIFFOpen</i>(3TIFF). The tag is identified by <i>tag</i>,
  62. one of the values defined in the include file <b>tiff.h</b>
  63. (see also the table below). The type and number of values
  64. returned is dependent on the tag being requested. The
  65. programming interface uses a variable argument list as
  66. prescribed by the <i>stdarg</i>(3) interface. The returned
  67. values should only be interpreted if <i>TIFFGetField</i>
  68. returns 1.</p>
