       TIFFFieldWriteCount - Get number of values to be written to field

       #include <tiffio.h>

       int TIFFFieldWriteCount(const TIFFField* fip)

       TIFFFieldWriteCount  returns  the  number  of values to be written into the specified TIFF
       field; that is, the number of arguments that should be supplied to TIFFSetField.  For most
       field types this is a small positive integer, typically 1 or 2, but there are some special
       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 TIFFSetField.
       TIFF_VARIABLE2  is the same as TIFF_VARIABLE except that the count argument must have type
       uint32.	(On most modern machines, this makes no practical difference, and the count argu-
       ment can simply be an int in either case.)
       TIFF_SPP  indicates  that  the  number of arguments must be equal to the image's number of
       samples per pixel.

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

       For  most  field  types, TIFFFieldWriteCount returns the same value as TIFFFieldReadCount,
       but there are some exceptions.

       TIFFFieldWriteCount returns an integer.
