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