NAME
       TIFFFieldReadCount - get number of values to be read from field


SYNOPSIS
          #include <tiffio.h>

       int TIFFFieldReadCount(const TIFFField *fip)


DESCRIPTION
       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 = -1 indicates that a variable number of values  is  possible;  then,  a  uint16_t  count
         argument and a pointer data argument must be supplied to TIFFGetField().

       • TIFF_VARIABLE2  =  -3  is  the  same  as  TIFF_VARIABLE  except  that the count argument must have type
         uint32_t.

       • TIFF_SPP = -2 indicates that the number of arguments is equal to the  image's  number  of  samples  per
         pixel.

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


RETURN VALUES
       TIFFFieldReadCount() returns an integer.
