Permanently deletes a file that has been marked for deletion.
#include <fsio.h>
int purgeerasedfile (
const char *path,
long sequence );
(IN) Points to the string containing either the absolute path (including the volume name) or the path name relative to the current working directory of the file to purge.
(IN) Uniquely identifies the file to purge.
If successful, returns 0. Otherwise, returns -1 and sets errno.
An application marks a file for deletion with a function such as remove. However, the server does not permanently delete a file until the server needs the disk space occupied by the file marked for deletion. A file marked for deletion can be recovered by calling the salvageerasedfile function.
The purgeerasedfile function permanently deletes a file marked for deletion. It frees the disk space that the deleted file occupied. A file deleted with purgeerasedfile cannot be recovered.
The value for the sequence parameter must be obtained from the scanerasedfiles function. The caller must have Delete rights to the file.
