dpns_creat - create a new DPNS file or reset it in the name server
#include <sys/types.h>
#include "dpns_api.h"
int dpns_creat (const char *path, mode_t mode)
int dpns_creatx (const char *path, mode_t mode, struct dpns_fileid *file_uniqueid)
dpns_creat creates a new DPNS file or resets it in the name server.
If the file exists, the length is truncated to 0 and the mode and owner are unchanged.
If the file does not exist yet, an entry is created in the name server database and the file's owner ID is set to the effective user ID of the requestor. The group ID of the file is set to the effective group ID of the requestor or is taken from the parent directory if the latter has the S_ISGID bit set.
The access permission bits for the file are taken from mode, then all bits set in the requestor's file mode creation mask are cleared (see dpns_umask(3)).
dpns_creatx behaves in the same way and returns the file unique id (name server hostname and file id).
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.
