High-Level Screen Management Intrinsic Library Reference Manual (32424-90002)

3- 9
returnpak A compound parameter that passes information
back from the intrinsic to the application.
For a complete description of this parameter,
see "Global Parameters" in Chapter 3.
termpak 5 A compound parameter that passes information to
the intrinsic.
termfile An 88-byte character
array
that indicates the
name of the device to
be enabled.
bypassfeature A four-byte integer
that is used by the
application to
indicate the
intrinsic features
you do not want to
use.
0 = ignore
1
or 3 = do not enable touch sensing
2
or 3 = do not clear device screen
devconfig A compound parameter that provides input to and
and receives output from the intrinsic.
allolen A four-byte integer
that indicates the
size in bytes of the
allocated
configuration storage
area.
actualen A four-byte integer
that indicates in
bytes the actual
configuration data
captured.
configarea An array that
represents the area
allocated by the
application to retain
device configuration
information. A
minimum of 800 bytes
is required.
Discussion
HPDENABLETERM opens the device as a file and places the device in block
mode. Once the device is opened and controlled by the Hi-Li intrinsics,
you should not call system intrinsics such as FREAD and FWRITE to
communicate with the terminal. All device I/O for the opened device must
be performed through Hi-Li. If HPDENABLETERM is the first Hi-Li
intrinsic called, the
comarea in globalpak is configured.
In addition to opening a device, you can also use this parameter to
request that the intrinsic read and return to the application function
