#DEVICEINFO Built-In Function

Use #DEVICEINFO to obtain information about a device.

option

identifies the specific information you are requesting. It must be one of these:

AUDITED

requests the value of the AUDITED flag of the specified device or file. If the

AUDITED flag is set for a device, files audited by the TMF subsystem can

reside on the device. If the AUDITED flag is set for a file, the file is audited by

TMF. For more information, see the TMF Reference Manual.

DEVICETYPE

requests the device type.

RECORDLENGTH

requests the device physical record length, in bytes.

SUBTYPE

requests the device subtype.

Device type and subtype are represented as decimal integers; see the

Guardian Procedure Calls Reference Manual for the type and subtype values.

device-name

is the syntactically correct name of a device to be examined (or the process that

drives it).

file-name

is the syntactically correct name of a file stored on the device to be examined.

Result

#DEVICEINFO returns the information requested by the options. If you specify more

than one option, #DEVICEINFO lists the items of information, separated by spaces, in

the same order as the option requests. If you specify a device or file that does not

exist, or if an error occurs, #DEVICEINFO returns the following:

•

0 for AUDITED, DEVICETYPE, and SUBTYPE

•

132 for RECORDLENGTH
