extent-spec
is the size of the file extents allocated to the file. The formats for extent-
spec are:
EXT [(] pri-extent-size [)]
EXT ( [ pri-extent-size ] , sec-extent-size )
pri-extent-size
is the size of the first file extent to be allocated to the file (the primary
extent). The value is an integer in the range 1 through 65535.
sec-extent-size
is the size of the extents allocated to the file after the primary extent is
allocated. The value is an integer in the range 1 through 65535.
exclusion-spec
is the exclusion mode for logical-unit. It determines the circumstances in
which other processes can access the file. The possible values for
exclusion-spec are the following:
EXCLUSIVE
SHARED
PROTECTED
EXCLUSIVE
means that no other processes can access actual-file-name while the
program containing logical-unit has the file open.
SHARED
means that other processes can both read from and write to actual-
file-name while the program containing logical-unit has the file
open.
PROTECTED
means that another process can read, but not write to, actual-file-
name while the program containing logical-unit has the file open.
See the Enscribe Programmer's Guide for more information about exclusion
modes.
