Warning:
This function is currently not documented; only its argument list is available.
Parameters
- path
-
Path for the new node(file).
- mode
-
Specifies both the permissions to use and the type of node to be created. It should be a combination (using bitwise OR) of one of the file types listed below and the permissions for the new node(e.g. 0640). Possible file types are: EIO_S_IFREG(regular file), EIO_S_IFCHR(character file), EIO_S_IFBLK(block special file), EIO_S_IFIFO(FIFO - named pipe) and EIO_S_IFSOCK(UNIX domain socket). To specify permissions EIO_S_I* constants could be used.
- dev
-
If the file type is EIO_S_IFCHR or EIO_S_IFBLK then dev specifies the major and minor numbers of the newly created device special file. Otherwise dev ignored. See mknod(2) man page for details.
- pri
-
The request priority: EIO_PRI_DEFAULT, EIO_PRI_MIN, EIO_PRI_MAX, or null. If null passed, pri internally is set to EIO_PRI_DEFAULT.
- callback
-
callback function is called when the request is done. It should match the following prototype:
void callback(mixed $data, int $result[, resource $req]);- data
is custom data passed to the request.
- result
request-specific result value; basically, the value returned by corresponding system call.
- req
is optional request resource which can be used with functions like eio_get_last_error
- data
-
Arbitrary variable passed to callback.
Return Values
eio_mknod returns request resource on success, or false on failure.
