说明

bool posix_mknod ( string $pathname , int $mode [, int $major [, int $minor ]] )

Creates a special or ordinary file.

参数

pathname: The file to create
mode: This parameter is constructed by a bitwise OR between file type (one of the following constants: POSIX_S_IFREG, POSIX_S_IFCHR, POSIX_S_IFBLK, POSIX_S_IFIFO or POSIX_S_IFSOCK) and permissions.
major: The major device kernel identifier (required to pass when using S_IFCHR or S_IFBLK).
minor: The minor device kernel identifier (defaults to 0).

返回值

如果成功则返回 TRUE，失败则返回 FALSE。

范例

Example#1 A posix_mknod() example


<?php

$file = '/tmp/tmpfile';  // file name
$type = POSIX_S_IFBLK;   // file type
$permissions = 0777;     // octal
$major = 1;
$minor = 8;              // /dev/random

if (!posix_mknod($file, $type | $permissions, $major, $minor)) {
    die('Error ' . posix_get_last_error() . ': ' . posix_strerror(posix_get_last_error()));
}

?>
