TIFFSetDirectory(3TIFF) TIFFSetDirectory(3TIFF)

NAME

TIFFSetDirectory, TIFFSetSubDirectory - set the current directory for
an open TIFF file

SYNOPSIS

#include <tiffio.h>

int TIFFSetDirectory(TIFF *tif, tdir_t dirnum)
int TIFFSetSubDirectory(TIFF *tif, uint64_t diroff)

DESCRIPTION

TIFFSetDirectory changes the current directory and reads its contents
with TIFFReadDirectory. The parameter dirnum specifies the
subfile/directory as an integer number, with the first directory
numbered zero.

TIFFSetSubDirectory acts like TIFFSetDirectory, except the directory
is specified as a file offset instead of an index; this is required
for accessing subdirectories linked through a SubIFD tag.

RETURN VALUES

On successful return 1 is returned. Otherwise, 0 is returned if
dirnum or diroff specifies a non-existent directory, or if an error
was encountered while reading the directory's contents.

DIAGNOSTICS

All error messages are directed to the TIFFError(3TIFF) routine.

%s: Error fetching directory count. An error was encountered while
reading the ``directory count'' field.

%s: Error fetching directory link. An error was encountered while
reading the ``link value'' that points to the next directory in a
file.
