L_LTKRN_API L_INT L_SetTempDirectory(pszTempDir)

Sets the directory in which LEADTOOLS will create temporary files.


L_TCHAR* pszTempDir

Character string that contains the temporary directory name. This should be a valid directory name and the directory should exist. It cannot be NULL.


Files used to store bitmaps of type TYPE_DISK will be created here. Also, disk tiles for TYPE_TILED bitmaps will be created here.

This function will have no effect on any existing bitmaps. The files associated with the existing bitmaps stay where they were. The new temporary directory will be used for creating new bitmaps.

If the image is allocated as TYPE_DISK, then the image should not be used in multiple threads.

Use L_SetTempFileOptions to control whether the temporary files are kept on disk, in memory or a combination of disk and memory. See the TEMPFILEOPTIONS topic for more information.
