|
* See your C library manual for more details about how remove() works
|
|
|
|
* on your system. On Unix, remove() removes also directories, as it
|
|
|
|
* calls unlink() for files and rmdir() for directories. On Windows,
|
|
|
|
* although remove() in the C library only works for files, this
|
|
|
|
* function tries first remove() and then if that fails rmdir(), and
|
|
|
|
* thus works for both files and directories. Note however, that on
|
|
|
|
* Windows, it is in general not possible to remove a file that is
|
|
|
|
* open to some process, or mapped into memory.
|
|
|
|
*
|
|
|
|
* If this function fails on Windows you can't infer too much from the
|
|
|
|
* errno value. rmdir() is tried regardless of what caused remove() to
|
|
|
|
* fail. Any errno value set by remove() will be overwritten by that
|
|
|
|
* set by rmdir().
|
|
|
|
