posix_mknod - Create a special or ordinary file (POSIX.1)

SYNOPSIS

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

DESCRIPTION

	Creates a special or ordinary file.

PARAMETERS

	      o $pathname
		- The file to create

	      o $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.

	      o $major
		- The major device kernel identifier (required to pass when using S_IFCHR or S_IFBLK).

	      o $minor
		- The minor device kernel identifier.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      A posix_mknod(3) 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()));
	      }

	      ?>

NAME

       mknod - make a special file

SYNOPSIS

       mknod name b major minor

       mknod name c major minor

       mknod name p

DESCRIPTION

       mknod makes a directory entry for a special file.

OPTIONS

       The following options are supported:

       b    Create a block-type special file.

       c    Create a character-type special file.

       p    Create a FIFO (named pipe).

OPERANDS

       The following operands are supported:

       major	The major device number.

       minor	The  minor  device  number; can be either decimal or octal. The assignment of major device numbers is specific to each system. You
		must be the super-user to use this form of the command.

       name	A special file to be created.

USAGE

       See largefile(5) for the description of the behavior of mknod when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |

NOTES

       If mknod(2) is used to create a device, the major and minor device numbers are always interpreted by the kernel running on that machine.

       With the advent of physical device naming, it would be preferable to create a symbolic link to the physical name  of  the  device  (in  the
       /devices subtree) rather than using mknod.
