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