Guardian Procedure Calls Reference Manual

primary-info-maxlen
input
INT:value
specifies the length (in bytes) of the buffer pointed to by primary-info. If the buffer length
is too short for the full set of device attributes, the procedure returns as many values as will fit
in the buffer.
This parameter must be present if primary-info is present.
primary-info-len
output
INT .EXT:ref:1
returns the actual length (in bytes) of the buffer pointed to by primary-info.
This parameter must be present if primary-info is present.
backup-info
output
INT .EXT:ref:*
if present and if backup-info-maxlen is not 0, points to a buffer that returns a set of physical
device attributes obtained from the backup I/O process that supports the specified device. The
attribute values are returned in a contiguous array.
If this parameter is present, backup-info-maxlen and backup-info-len must also be
present.
The set of attributes for which values are returned in backup-info is identical to the set
returned in the primary-info parameter of this procedure and of the
DEVICE_GETINFOBYLDEV_ procedure. For a description of the attributes returned in
backup-info, see Device Attributes and Value Representations (page 304).
backup-info-maxlen
input
INT:value
specifies the length (in bytes) of the buffer pointed to by backup-info. If the buffer length is
too short for the full set of device attributes, the procedure returns as many values as will fit in
the buffer.
This parameter must be present if backup-info is present.
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.
error-detail
output
INT .EXT:ref:1
