To include an EDL file for the KasperskyOS kernel in a policy description, use the following declaration:
use EDL kl.core.Core
To include an EDL file for a program (such as a driver or application) into a policy description, use the following declaration:
use EDL <link to EDL file>
The link to the EDL file is the EDL file path (without the extension and dot before it) relative to the directory that is included in the set of directories where the nk-psl-gen-c compiler searches for PSL, IDL, CDL, and EDL files. (This set of directories is defined by the parameters -I <path to the directory> when starting the makekss script or the nk-psl-gen-c compiler.) A dot is used as a separator in a path description.
Example:
/* Include the UART.edl file, which is located
* in the KasperskyOS SDK at the path sysroot-*-kos/include/kl/drivers. */
use EDL kl.drivers.UART
/* The nk-psl-gen-c compiler must be configured to search for
* PSL, IDL, CDL, and EDL files in the sysroot-*-kos/include directory. */
The nk-psl-gen-c compiler finds IDL and CDL files through EDL files because EDL files contain links to the corresponding CDL and IDL files, and the CDL files contain links to the corresponding CDL and IDL files.
