NAME    [Toc]    [Back]

     clone - open any minor device on a	STREAMS	driver

DESCRIPTION    [Toc]    [Back]

     clone passes a minor number of 0 to the target driver, and	it is the
     responsibility of the target driver to select an unused minor number from
     the numbers it supports.

     clone generates an	ENXIO error, without opening the device, if the	minor
     device number provided does not correspond	to a valid major device, or if
     the driver	indicated is not a STREAMS driver.

CAVEATS    [Toc]    [Back]

     Multiple opens of the same	minor device cannot be done through the	clone
     interface.	 Executing stat(2) on the filesystem node for a	cloned device
     yields a different	result from executing fstat(2) using a file descriptor
     obtained from opening the node.
