# Introduction

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

The following C sample programs are provided:

- tstxtract
- filter

The source code and makefile (`program_name_platform.mak`) for the programs are in the directory `install\KeyviewFilterSDK\samples\program_name`, where `install` is the path name of the Filter installation directory, and `program_name` is the name of the sample program.

The executable for the programs is in the directory `install\KeyviewFilterSDK\OS\bin`, where `OS` is the name of the operating system.

To compile the sample programs, use the makefile provided for the appropriate platform. Make sure that the Filter `include` directory is specified in the include path of the project. After the executable is compiled and built, you must place it in the same directory as the Filter libraries.
