17.2 DLI Implementation and Reference Guide
Running DLI Sample Applications
Notes on each specific DLI sample follow below. You are not required to test any or all of them, but if
you do, we suggest running them in the order given below.
Some samples require one or more command-line arguments, and will prompt for them if not given.
You should find the following DLI samples in individual subfolders under
C:\Datalogics\APDFL7.0.0\DLI\Samples (or similar). On Windows platforms, a Visual Studio
Solution file for all DLI samples can be found in C:\Datalogics\APDFL7.0.0\DLI\Samples\All
(see dli_samples.sln).
NOTE: Sample applications included in each release are subject to change. Some
samples may not appear in releases on certain platforms.
Activating Files-in-Memory
In the MultiDoc sample, adding the command-line keyword "MEMORY" will run the application using
Files-in-Memory methods. This will make use of memory work files instead of I/O processing to disk, and
as a result should show improved processing times.
Within the sample, "MEMORY" is recognized as an indicator which then determines the calling arguments
for dlpdfinit, as shown in the following typical excerpt, where FileSystemType is defined as
eMemFileSys if MEMORY was found in the calling arguments for the application:
switch (FileSystemType)
{
case eStdFileSys:
pdfInstance=dlpdfinit(&DataRec, NULL, NULL);
break;
case eMemFileSys:
pdfInstance=dlpdfinit(&DataRec, dlpdfmemfilesys(), NULL);
break;
default:
printf("Unknown File System requested.");
return 8;
