Predefined Constants
The constants below are defined by this extension, and
will only be available when the extension has either
been compiled into PHP or dynamically loaded at runtime.
Request priority constants:
-
EIO_PRI_MIN
(int)
-
Request minimal prioriry
-
EIO_PRI_DEFAULT
(int)
-
Request default prioriry
-
EIO_PRI_MAX
(int)
-
Request maximal prioriry
eio_seek whence argument:
-
EIO_SEEK_SET
(int)
-
The offset is set to specified number of bytes(
offset).
-
EIO_SEEK_CUR
(int)
-
The offset is set to its current location plus
offset bytes.
-
EIO_SEEK_END
(int)
-
The offset is set to the size of the file plus
offset bytes.
Flags used with eio_readdir:
-
EIO_READDIR_DENTS
(int)
-
eio_readdir flag. If specified, the result argument of the callback
becomes an array with the following keys:
'names' - array of directory names
'dents' - array of struct eio_dirent-like
arrays having the following keys each:
'name' - the directory name;
'type' - one of EIO_DT_*
constants;
'inode' - the inode number, if available, otherwise
unspecified;
-
EIO_READDIR_DIRS_FIRST
(int)
-
When this flag is specified, the names will be returned in an order
where likely directories come first, in optimal stat order.
-
EIO_READDIR_STAT_ORDER
(int)
-
When this flag is specified, then the names will be returned in an order
suitable for
stat'ing each one. When planning to
stat all files in the given directory, the
returned order will likely be
fastest.
