Character specific version
Comments DTWAIN_SetTempFileDirectoryEx specifies the directory, lpszDir, where DTWAIN will create temporary files. These files are usually created by DTWAIN when creating multipage image files. The files that are created are destroyed by DTWAIN when no longer necessary. The CreationFlags are a set of boolean flags that can be applied to how the directory is created. Currently, the only flag available is DTWAIN_TEMPDIR_CREATEDIRECTORY, which when specified, will create the directory if the directory does not already exist. For example (C/C++ example), DTWAIN_SetTempFileDirectoryExA("c:\\SomeDirectory\\TempDir", DTWAIN_TEMPDIR_CREATEDIRECTORY); will create the directory "c:\SomeDirectory\TempDir" if it does not already exist. Without the DTWAIN_TEMPDIR_CREATEDIRECTORY flag, the directory must already exist for it to be set to the temporary file directory. To get the current directory name, call DTWAIN_GetTempFileDirectory.
TWAIN State Transitions None.
