TIFFFieldPassCount¶
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. (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).
