CLI User Exit functions are general purpose facilities that can be added to the CLI workstation architecture on the selected operating system. These functions allow user-defined processing to take place.
  1. Change directories to the sample directory:

    cd <prefix>/teradata/client/16.20/sample

  2. Modify the CliLgnEx.c or CliPPS.c file in the sample directory.
  3. Compile and link using either the 32-bit or 64-bit version of the makefile to create a new shared object, libtdusr.so.
    The Native compiler on IA64 is not supported.
    To compile the 32-bit version, type:

    make -f maketdusr.lx

    On 64-bit Red Hat Linux, the compiler always generates 64-bit binaries. The 32-bit makefile is not supported on 64-bit Red Hat Linux platforms.
  4. Move the libtdusr.so file into the cli installation directory, and verify that libcliv2 exists in the same directory.
  5. See "CLI Exit Functions" in Teradata® Call-Level Interface Version 2 Reference for Workstation-Attached Systems (B035-2418).
