NAME

       strsetup.conf - Configuration file for STREAMS drivers

DESCRIPTION

       The  /etc/strsetup.conf file is the configuration file for STREAMS drivers.  The strsetup.conf file specifies one or more character special
       files (or nodes) to be created when a STREAMS driver is configured into the kernel.  If the driver is not configured, no character  special
       files are created for it.  If an old version of the file exists, the strsetup command removes it before the new one is created.

       The  /etc/strsetup.conf file is defined as a Context-Dependent Symbolic Link (CDSL), and must be maintained as such.  See the System Admin-
       istration manual for more information.

       Each entry in the /etc/strsetup.conf file specifies a driver name, device special file name, file mode and minor number.  See the  EXAMPLES
       section for a sample strsetup.conf file.

       Each line in the file is of the form:

       driver_name filename file_mode minor_number

       The  fields  have  the  following meanings: Specifies the name of the driver as reported by the strsetup -c command.  This field is used to
       match the names read by the strsetup command from the kernel and must match exactly (the match is case sensitive).  Specifies the full path
       name  of  the  character  special file or files to be created when driver_name is configured into the kernel.  The filename can contain one
       conversion specifier in the style of printf(3).	This conversion is used to include a minor device number in the filename.   The  permitted
       conversions are the following: Prints the minor number as a signed decimal Prints the minor number as a hexadecimal with lower case letters
       Prints the minor number hexadecimal with uppercase letters Prints octal Prints the minor number as an unsigned  decimal	Prints	the  minor
       number as a signed decimal
       Note  that  you	must  use a double percent sign (%%) to include a percent sign in the filename.  Optionally, each of these conversions can
       include a specification for some number of leading 0's.
       This is done by following the % with a 0 and one or more digits specifying the total number of digits to be printed.   The  0  must  appear
       after the %.  See the printf(3) reference page for more information.
       Any  directories  in  the path of the filename that do not exist are created.  Specifies the file mode assigned to the file when it is cre-
       ated.  The file_mode field must always be in octal.  The file is always created as a character special file.  Specifies	the  minor  device
       number  field.	The  strsetup command reads the major device numbers from the kernel.  This field indicates to the strsetup command how to
       assign minor device numbers.  This minor_number field can contain the one of the following values: Indicates that the device should be cre-
       ated  as  a clone device.  In this case the major number becomes that of the special clone pseudo-device driver and the minor device number
       becomes the device's major number.  Note that the word clone must be lowercase.	Creates a single device with the minor	device	number	N.
       Note  that  N  is a decimal number.  Create M-N nodes with the devices' major numbers and minor numbers between M and N.  Note that M and N
       are decimal numbers.  When a range of minor numbers is specified, a filename conversion specifier can be used to  make  certain	that  each
       node created is unique.

EXAMPLES

       The following is a sample /etc/strsetup.conf file:
			special  driver  name	    filename		 file mode	 minor number ptm	      /dev/ptmx 	      0666
       clone log	     /dev/streams/log	     0666	     clone  nuls	     /dev/streams/nuls	      0666	       clone  echo
       /dev/streams/echo	0666		 clone	sad		 /dev/sad/admin 	 0666		 clone pts	       /dev/pts/%d
       0666	       0-127
