Vordefinierte Konstanten

Folgende Konstanten werden von dieser Erweiterung definiert und stehen nur zur Verfügung, wenn die Erweiterung entweder statisch in PHP kompiliert oder dynamisch zur Laufzeit geladen wurde.

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.

EIO_READDIR_FOUND_UNKNOWN (int)

EIO_DT_UNKNOWN (int)

Unknown node type(very common). Further stat() needed.

EIO_DT_FIFO (int)

FIFO node type

EIO_DT_CHR (int)

Node type

EIO_DT_MPC (int)

Multiplexed char device (v7+coherent) node type

EIO_DT_DIR (int)

Directory node type

EIO_DT_NAM (int)

Xenix special named file node type

EIO_DT_BLK (int)

Node type

EIO_DT_MPB (int)

Multiplexed block device (v7+coherent)

EIO_DT_REG (int)

Node type

EIO_DT_NWK (int)

EIO_DT_CMP (int)

HP-UX network special node type

EIO_DT_LNK (int)

Link node type

EIO_DT_SOCK (int)

Socket node type

EIO_DT_DOOR (int)

Solaris door node type

EIO_DT_WHT (int)

Node type

EIO_DT_MAX (int)

Highest node type value

Hinweis:

EIO_S_I* constants have the same meaning as their S_I* POSIX counterparts.

Hinweis:

EIO_SYNC_FILE_* constants have the same meaning as their SYNC_FILE_** counterparts.

Hinweis:

EIO_O_* constants have the same meaning as their O_* POSIX counterparts.
