NAME

sad - STREAMS Administrative Driver

SYNOPSIS

#include

int ioctl(int fildes, int command, int arg);

DESCRIPTION

The STREAMS Administrative Driver provides an interface for applications to perform administrative operations on STREAMS modules and drivers. The interface is provided through ioctl(2) commands. Privileged operations may access

the sad driver using /dev/sad/admin. Unprivileged operations

may access the sad driver using /dev/sad/user.

The fildes argument is an open file descriptor that refers

to the sad driver. The command argument determines the

control function to be performed as described below. The arg argument represents additional information that is needed by this command. The type of arg depends upon the command, but it is generally an integer or a pointer to a

command-specific data structure.

COMMAND FUNCTIONS

The autopush facility (see autopush(1M)) allows one to con-

figure a list of modules to be automatically pushed on a

stream when a driver is first opened. Autopush is con-

trolled by the following commands:

SAD_SAP Allows the administrator to configure the given

device's autopush information. arg points to a strapush structure, which contains the following members:

unit_t ap_cmd;

major_t sap_major;

minor_t sap_minor;

minor_t sap_lastminor;

unit_t sap_npush;

unit_t sap_list [MAXAPUSH] [FMNAMESZ + 1];

The sap_cmd field indicates the type of confi-

guration being done. It may take on one of the following values:

SAP_ONE Configure one minor device of a

driver.

SAP_RANGE Configure a range of minor devices

of a driver.

SAP_ALL Configure all minor devices of a

driver.

SAP_CLEAR Undo configuration information for a

driver.

The sap_major field is the major device number

of the device to be configured. The sap_minor

field is the minor device number of the device to

be configured. The sap_lastminor field is used

only with the SAP_RANGE command, which config-

ures a range of minor devices between sap_minor

and sap_lastminor, inclusive. The minor fields

have no meaning for the SAP_ALL command. The

sap_npush field indicates the number of modules

to be automatically pushed when the device is

opened. It must be less than or equal to MAXA-

PUSH , defined in sad.h. It must also be less

than or equal to NSTRPUSH, the maximum number of modules that can be pushed on a stream, defined

in the kernel master file. The field sap_list

is an array of NULL-terminated module names to be

pushed in the order in which they appear in the list.

When using the SAP_CLEAR command, the user sets

only sap_major and sap_minor. This will undo the

configuration information for any of the other commands. If a previous entry was configured as

SAP_ALL, sap_minor should be set to zero. If a

previous entry was configured as SAP_RANGE ,

sap_minor should be set to the lowest minor dev-

ice number in the range configured. On failure, errno is set to the following value:

Devices sad(7D)

EFAULT arg points outside the allocated address space. EINVAL The major device number is invalid, the number of modules is invalid, or the list of module names is invalid. ENOSTR The major device number does not represent a STREAMS driver.

EEXIST The major-minor device pair is already

configured.

ERANGE The command is SAP_RANGE and

sap_lastminor is not greater than

sap_minor, or the command is SAP_CLEAR

and sap_minor is not equal to the

first minor in the range.

ENODEV The command is SAP_CLEAR and the dev-

ice is not configured for autopush. ENOSR An internal autopush data structure cannot be allocated.

SAD_GAP Allows any user to query the sad driver to get

the autopush configuration information for a given device. arg points to a strapush structure as described in the previous command.

The user should set the sap_major and sap_minor

fields of the strapush structure to the major and minor device numbers, respectively, of the device in question. On return, the strapush structure will be filled in with the entire information used to configure the device. Unused entries in

the module list will be zero-filled.

On failure, errno is set to one of the following values: EFAULT arg points outside the allocated address space.

EINVAL The major device number is invalid. ENOSTR The major device number does not represent a STREAMS driver.

ENODEV The device is not configured for auto-

push.

SAD_VML Allows any user to validate a list of modules

(that is, to see if they are installed on the

system). arg is a pointer to a str_list struc-

ture with the following members:

int sl_nmods;

struct str_mlist *sl_modlist;

The str_mlist structure has the following

member:

char l_name[FMNAMESZ+1];

sl_nmods indicates the number of entries the user

has allocated in the array and sl_modlist points

to the array of module names. The return value is 0 if the list is valid, 1 if the list contains an

invalid module name, or -1 on failure. On

failure, errno is set to one of the following values: EFAULT arg points outside the allocated address space.

EINVAL The sl_nmods field of the str_list

structure is less than or equal to zero.
