NAME

       TIFFFieldPassCount - Get whether to pass a count to TIFFGet/SetField

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,   or
       TIFFFieldWithName.

       When  a  count is required, it will be of type uint32 when TIFFFieldReadCount reports TIFF_VARIABLE2, and
       of type uint16 otherwise.  (This distinction is critical for use of TIFFGetField, but normally not so for
       use of TIFFSetField.)

RETURN VALUES

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