NAME

       TIFFFieldPassCount - get whether to pass a count to TIFFGetField/TIFFSetField

SYNOPSIS

          #include <tiffio.h>

       int TIFFFieldPassCount(const TIFFField *fip)

DESCRIPTION

       TIFFFieldPassCount()  returns true (nonzero) if TIFFGetField() and TIFFSetField() expect a count value to
       be passed before the actual data pointer.

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

       When a count is required, it will be of type uint32_t if TIFFFieldReadCount() reports TIFF_VARIABLE2, and
       of   type   uint16_t  otherwise.   Use  TIFFFieldWriteCount()  for  TIFFSetField(),  respectively.  (This
       distinction is critical for use of TIFFGetField(), but normally not so for use of TIFFSetField().)

       An alternative function for the count value determination is TIFFFieldSetGetCountSize().

RETURN VALUES

       TIFFFieldPassCount() returns an integer that is always 1 (true) or 0 (false).
