# Introduction

The sample programs demonstrate how to use the C implementations of PDF Export. The sample code is intended to provide a starting point for your own applications or to be used for reference purposes.

The source code and makefile for each program are in the following directory, where `install` is the path of the Export installation directory, and `program_name` is the name of the sample program:

    install\pdfexport\programs\program_name

## C Sample Programs

The C sample programs demonstrate how to use the C implementation of PDF Export. The following sample programs are provided:

- cnv2pdf

You can use the `cnv2pdf` sample program on Windows and UNIX.

NOTE: The sample programs do not parse white space in file names. If your file names contain spaces, use quotation marks around the entire path name. Inserting quotation marks around the file name only does not work.

The sample programs pass license information to KeyView using `fpInitWithLicenseData()`. This is the method recommended by Micro Focus. Before the sample programs can be compiled, you must replace the parameters `YOUR_LICENSE_ORGANIZATION` and `YOUR_LICENSE_KEY` in the `fpInitWithLicenseData()` function call with your license information.

To compile the sample programs, use the makefiles provided in the sample programs' directory. Ensure the PDF Export `include` directory is specified in the include path of the project. After the executables are compiled and built, you must place them in the same directory as the PDF Export libraries.

NOTE: Compiled binaries are provided for some of the sample programs, in the `PLATFORM/bin` folder. These have an embedded trial license, which expires approximately five months after release.
