fip)

<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>

TIFFFieldReadCount
returns the number of values available to be read from the
specified TIFF field; that is, the number of arguments that
should be supplied to TIFFGetField. For most field
types this is a small positive integer, typically 1 or 2,
but there are some special values: 
TIFF_VARIABLE indicates that a variable number of values
is possible; then, a uint16 count argument and
a pointer data argument must be supplied to
TIFFGetField. 
TIFF_VARIABLE2 is the same as TIFF_VARIABLE
except that the count argument must have type
uint32. 
TIFF_SPP indicates that the number of arguments is equal
to the image&rsquo;s number of samples per pixel.

fip is a
field information pointer previously returned by
TIFFFindField, TIFFFieldWithTag, or
TIFFFieldWithName.

<h2>RETURN VALUES
