TIFFFieldWriteCount(3TIFF)                          TIFFFieldWriteCount(3TIFF)

NAME
       TIFFFieldWriteCount - Get number of values to be written to field

SYNOPSIS
       #include <tiffio.h>

       int TIFFFieldWriteCount(const TIFFField* fip)

DESCRIPTION
       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 posi-
       tive 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 sup-
       plied to TIFFSetField.
       TIFF_VARIABLE2 is the same as TIFF_VARIABLE except that the count argu-
       ment  must  have  type uint32.  (On most modern machines, this makes no
       practical difference, and the count argument 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  TIFFFind-
       Field, TIFFFieldWithTag, or TIFFFieldWithName.

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

RETURN VALUES
       TIFFFieldWriteCount returns an integer.
