Guardian Procedure Calls Reference Manual

backup-info-len
output
INT .EXT:ref:1
returns the actual length (in bytes) of the buffer pointed to by backup-info.
This parameter must be present if backup-info is present.
timeout
input
INT(32):value
specifies how many hundredths of a second the procedure should wait for a response from the
I/O process. The maximum value is 2147483647. The default value is 6000D (one minute).
A value of -1D causes the procedure to wait indefinitely.
options
input
INT:value
specifies options. The bits, when set, indicate:
Reserved (specify 0).<0:12>
Specifies that the procedure search for the next device that has a subtype of match-subtype.
options.<15> must be equal to 1 and match-subtype must be specified when this option is used.
<13>
Specifies that the procedure search for the next device that has a type of match-type. options.<15>
must be equal to 1 and match-type must be specified when this option is used.
<14>
Specifies that the procedure search for the next device that matches the selection criteria. The search
begins with the logical device number immediately following the one specified by the ldevnum parameter.
<15>
This option can be used alone or in combination with options.<13> or options.<14>. See
Considerations (page 307).
The default value of options is 0.
match-type
input
INT:value
if present and if not -1, specifies a device type that is to be used as a search criterion. Supplying
match-type causes the procedure to return information for the next device that has a device
type of match-type and a logical device number greater than ldevnum.
options.<14> and options.<15> must both be equal to 1 in order to use this parameter.
match-type can also be used in combination with match-subtype. See Considerations
(page 307).
match-subtype
input
INT:value
if present and if not -1, specifies a device subtype that is to be used as a search criterion.
Supplying match-subtype causes the procedure to return information for the next device
that has a device subtype of match-subtype and a logical device number greater than
ldevnum.
options.<13> and options.<15> must both be equal to 1 in order to use this parameter.
match-subtype can also be used in combination with match-type. See Considerations.
