michael@0 13 * OpenAnonymousTemporaryFile
michael@0 14 *
michael@0 15 * Creates and opens a temporary file which has a random name. Callers have no
michael@0 16 * control over the file name, and the file is opened in a temporary location
michael@0 17 * which is appropriate for the platform.
michael@0 18 *
michael@0 19 * Upon success, aOutFileDesc contains an opened handle to the temporary file.
michael@0 20 * The caller is responsible for closing the file when they're finished with it.
michael@0 21 *
michael@0 22 * The file will be deleted when the file handle is closed. On non-Windows
michael@0 23 * platforms the file will be unlinked before this function returns. On Windows
michael@0 24 * the OS supplied delete-on-close mechanism is unreliable if the application
michael@0 25 * crashes or the computer power cycles unexpectedly, so unopened temporary
michael@0 26 * files are purged at some time after application startup.
